how are electromagnetic waves different from sound waves?

2) Sound waves are elastic waves and propagate through actual vibrations of constituent particles in the medium it travels though. The EM waves on the other hand are due to oscillating electric and magnetic fields perpendicular mutually and also to the direction of motion.

Sound and light are similar in that both are forms of energy that travel in waves. They both have properties of wavelength, freqency and amplitude. ... Sound can only travel through a medium (substance) while light can travel through empty space. Sound is a form of mechanical energy caused by vibrations of matter.

EM waves are made up of oscillating electromagnetic and magnetic fields, whereas mechanical waves are just fluctuations in a medium. EM waves travel at the speed of light 3x10^8 m/s, whereas mechanical waves travel slower.

Matter waves are quite different from electromagnetic waves. Electromagnetic waves have larger wavelengths. Unlike electromagnetic waves matter waves don't exist in vacuum. ... Thats why matter waves cannot be electromagnetic.

Electromagnetic waves are waves that have no medium to travel whereas mechanical waves need a medium for its transmission. ... While an electromagnetic wave is called just a disturbance, a mechanical wave is considered a periodic disturbance.

Most of the mathematics and properties of mechanical waves apply to light waves. Light waves are different from mechanical waves, however, because they can travel through a vacuum. Light waves are just one type of electromagnetic wave.

Sound waves are examples of mechanical waves while light waves are examples of electromagnetic waves. Electromagnetic waves are created by the vibration of an electric charge. This vibration creates a wave which has both an electric and a magnetic component.

Electromagnetic waves are waves that consist of vibrating electric and magnetic fields. They transfer energy through matter or across space. The transfer of energy by electromagnetic waves is called electromagnetic radiation. ... When it travels through space, it doesn't lose energy to a medium as a mechanical wave does.

Electromagnetic Waves have different wavelengths. Radio waves, television waves, and microwaves are all types of electromagnetic waves. They only differ from each other in wavelength. Wavelength is the distance between one wave crest to the next.

Sound waves are longitudinal waves that is, are transmitted in the same direction of oscillation of the particles in the medium. Electromagnetic waves are transverse ie, the electric and magnetic fields, which are perpendicular to each other, oscillate perpendicularly to the direction of wave propagation.

Why do sound waves travel slower than EM waves? Sound waves must have a material medium to propagate. ... It takes time to accelerate the molecules and create a compression wave. EM waves can propagate in vacuum where they use the ultimate speed limit of energy propagation in nature, the speed of light.

Waves are moving energy. Light waves are unique in their ability to travel through a vacuum (space). Sound is a form of energy that results when vibrating materials produce waves that move through matter.

Sound and light are similar in that both are forms of energy that travel in waves. They both have properties of wavelength, freqency and amplitude. Here are some differences: Sound can only travel through a medium (substance) while light can travel through empty space.

For example water waves propagate in water, whereas EM waves can exist in a vacuum. EM waves are made up of oscillating electromagnetic and magnetic fields, whereas mechanical waves are just fluctuations in a medium.

Why do sound waves travel slower than EM waves? Sound waves must have a material medium to propagate. They compress and decompress the medium. ... EM waves can propagate in vacuum where they use the ultimate speed limit of energy propagation in nature, the speed of light.

EM waves do not propagate in a medium, whereas mechanical waves need one to exist. For example water waves propagate in water, whereas EM waves can exist in a vacuum. EM waves are made up of oscillating electromagnetic and magnetic fields, whereas mechanical waves are just fluctuations in a medium.

Electromagnetic waves can travel through a vacuum, that is an empty space, whereas mechanical waves cannot. They need a medium to travel such as water or air. Ripples in a pond are an example of mechanical waves whereas electromagnetic waves include light and radio signals, which can travel through the vacuum of space.
