What is the fundamental difference between radio wave and sound wave?

A radio wave is electromagnetic radiation.\n\nA sound wave is variations in the density of the air that it is traveling through.

Radio waves are those radiation waves not visible using the unaided eye:they are ouside of the visual range.TV stations uses radio waves to transmit a signal,but it is the TV set reciever itself that recieves that signal and processes it so that it can be seen.\nHave you ever seen a radio wave?\nThe refracting and reflecting telescopes use visual light.\nThe spectroscope breaks up visible light into its constituant colors and you can see them.\nThe universe is full of radio noise and waves that are an echo of the beginning of the universe.\nTo help you understand:all light is radiation as are all other methods of transmitting any kind of radiant force.\nX-Rays,Gamma waves,neutrons et. al. all radiate out from a source.Sunlight is merely radiation that we can see,the sun is full of radio transmissions that are unseen.\nPS:The leaves of a Black Eyed Susan radiate out from the center.

Light and radio signals are all the same thing, electromagnetic radiation. Radio waves are just very low frequency light and light is just very high frequency radio signals. All objects that are hotter than absolute zero give off some electromagnetic radiation. The really hot objects give off visible light. Cooler ones give off infra red light. Cooler still and you get radio emissions. The Earth's surface gives off radio waves because it is warm. In fact, it gives off so much that it is an interference for communication satellites trying to hear signals from the ground.\n\nModern radio astronomy uses giant antennas to focus radio waves, just like optical telescopes focus visible light. Computers are used to construct images of what the sky would look like if your eyes could see radio waves.

If the frequency remains the same, the larger the amplitude, the more energy.  This is from basic observation of an AM radio signal - silence, not much change to the carrier, but the louder the signal being transmitted, the larger amplitude of the signal.

Electromagnetic (EM) waves range from radio to gamma.\n\nThey are all EM waves.\n\nIt is more correct to say that radio is low frequency EM and light is mid frequency EM.

Sound is a form of energy which is audible that is it can be registered by the ear. It travels in a medium and cannot travel in vaccuum. It is propagated in air as a series of compression and rarefaction (or expansion zones) these zones exist along the line joining the source and observer.\n\nIt is hard to localise sound unlike light because sound travels due to the disturbance of the material particles themselves.\n\nSound travels faster in a denser medium.

In both cases, information (music, voice, video, whatever) is carried in radio waves (electromagnetic waves).  Think of waves on the beach.  They can differ in the height (amplitude) of the waves, and in the frequency of the waves (how close the waves are to each other).\n\nIn amplitude modulation (AM) ... the information is carried in the changes (modulation) of the amplitude of the radio waves.  All the waves from a particular radio source (e.g. a radio station) all have the same frequency, but different amplitude.\n\nIn frequency modulation (FM) ... the information is carried in the changes (modulation) of the frequency of the radio waves.   All the waves from a certain radio source have the same amplitude, but different frequency.

Sound waves can be heared but cannot be seen, only light and colors are seen. We can only see the motions, oscillations and vibrations on the objects caused by sound waves.♥\n\nCheck out these links:\nhttp://www.du.edu/~jcalvert/waves/soundwav.htm\nhttp://www.glenbrook.k12.il.us/gbssci/phys/Class/sound/u11l1a.html\nhttp://www.du.edu/~jcalvert/waves/soundwav.htm

All the waves you have mentioned, are electomagnetic waves. They differ in their frequency, this means, their energy. Therefore, you cannot have a radio wave the same frequency as a visible wave, its one or the other, the frequency will indicate if its radio, infrared, visible and so on. The differnt frequencies gives them their particular properties. All of them travel at the same speed.

Actually, to correct a previous answer, waves in water travel faster than waves in air because the propagation velocity is proportional to the medium density. \n\nSounds produced by a gas modulating larynx are bubbled out of ones mouth underwater. Acoustic energy is transferred from air to water as they emerge from the mouth. there is an impedance mismatch at this point. Also the shape of the bubble emergence guarantees that this is not a very linear transmission mechanism. The result is nonlinear attenuation and spectral dispersion which results in muffling of the signal.\n\nIf you were to use an underwater transducer (speaker) and send your acoustic signal (using a mic and amplifier above water), the intended receiver would hear it with good fidelity since there is no gas/water boundary to cross in this scenario.\n\nHope this helps

The RF waves emanating from an antenna are generated by the movement of electrical charges in the antenna. Electromagnetic waves can be characterized by a wavelength and a frequency. The wavelength is the distance covered by one complete cycle of the electromagnetic wave, while the frequency is the number of electromagnetic waves passing a given point in one second. The frequency of an RF signal is usually expressed in terms of a unit called the "hertz" (abbreviated "Hz"). One Hz equals one cycle per second. One megahertz ("MHz") equals one million cycles per second.

Not at all.\n\nSound and light are two totally diiferent types of waves.\n\nSonic wave is a disturbance in a medium (in our situation most commonly air).\n\nLight is electromagnetic wave and needs no medium.

Sound waves are longitudinal waves. They vibrate back and forth in the direction that they aremoving. Sound travels at about 1100 feet /sec.\n\nLight waves are transverse waves, part of the electromagnetic spectrum. they vibrate up and down similar to water waves. They travel at 186,000 miles/sec.

bats detect the presence of an obstacle by hearing the echo of the sound produced by them. this process is called sound ranging. as ultrasonic waves are used bcoz they have frquency above20000 hz and travel undeviated through long distances and can b confined to a narrow beam since they r not easily absorbed in an medium.light wave is a transverse wave.its a wave in which each particle of medium executes vibrations in the direction perpendicular to the direction of propagation of the wave. and sound wave is alongitudinal wave.its a wave in which each particle of the medium executes vibration about its mean position in direction of propagation of the wave.

Like light rays radio waves are reflected refracted and diffracted and absorbed by materials. At certain angle of reflection radio waves are also polarized.\n\nSince it is an E.M wave it travels in vacuum or air with velocity C.\n\nThey are reflected by metals, but absorbed by many substances like wall. The absorption depends upon the thickness of the material.Usually the thicknes of a wall is such as to absorb radio waves. \n\nBecause of long wavelength it can bend across obstacles, and even small cleavage in a wall can fill a room with radio waves.

Aside from circuitry considerations (which can not be ignored) short waves are more penetrating than long waves.  For example light waves and X-rays are both electromagnetic but the shorter X-rays can penetrate flesh and bone.  short UV waves penetrate clouds to give you a sunburn on a less than sunny day.  Short microwaves penetrate food in an oven right through the container.  A piccolo can be heard easily above an entire marching band (as in Stars and Stripes Forever).  Therefore, the microphone is more apt to "hear" higher tones and amplify them even more than low tones and hear them from the speaker even louder, etc. etc.

the wavelength is half...\n\nvavelength and frequency are inversely proportional
