what is the relation between thewave length of electromagnetic radiation and the energy of a wave?

lower wavelength is higher energy.  Planck's law holds that Energy equals a constant (Planck's constant or h) times frequency.  Frequency is inversely proportional to wavelength, so wavelength is inversely proportional to Energy.\n\nIn practical terms, I remember this because blue and ultraviolet light is higher energy than red and infrared.

HAHAHAH ARE YOU TRYING TO TEST US?\n\nLight is a form of electromagnetic radiation: i.e. it has oscillating electric(E) and magnetic(B) fields that travel through  space at speed c with the same frequency and wavelength.\nrotational energy of light if I am not worng...I like that sh.t!!good question\nRotational energy level gaps typically\n\n \n\nDE = 10^-23 J\n\nTherefore n = 1.5 x 10^10 s^-1

The energy contained within a single photon of light can be found using Planck's equations,\nE = hv\nWhere E is the energy, h is Planck's constant, and v is the frequency of the light.\n\nYou can see that the higher the frequency of light, the higher the energy per photon.\nExamining the spectrum of light one can see that green light (roughly a wavelength of 550 nm) has a higher frequency than orange light (roughly a wavelength of 650 nm).\nTherefore, green light photons contain more energy than orange light photons.\n\nPlanck's constant = h = 6.626 E-34 J s

heat is not electromagnetic radiation, it's molecular kinetic energy (or thermal energy).  The sun emits Ultraviolet radiation, amongst other emissions in the light spectra, but i don't believe the heat emitted can be attributed to an electromagnetic wave.

Energy is directly proportinal to the square of velocity as you know (Kinetic Energy)\nas far as the velocity of a wave is concerned it wavelength * frequency\nso it has to be either frequency or wavelength,the choice is left to you\nif u asked me i had rather choose to go with frequency

In a transverse wave, the wavelength is the distance between the crests (or troughs) of the wave.\n\nThe frequency is the number of times a wave passes in a certain amount of time.

The wave length is the distance between two  consecutive points which are in same phase.\n\nThe wave pattern repeats itself after one wavelength.\n\nThus we can consider this as one cycle of operation. \n\nOne cycle corresponds to 2pi radian or 360 degree.\n\nThus a wave length ( Lambda) corresponds to 2pi radian\n\nAny orbitrary length l corresponds to( 2 pi/ lambda ) x l\n\nThe path differnce l is equivalent to a phase difference of  ( 2 pi/ lambda ) x l\n\nA phase difference of Theta corresponds to a path difference of  ( Lambda/2pi ) x theta.

maxwell eqn \nther is no need to rember  it 's of no use\n till you pass out of school\nbandwidth it's the range of length within \nwhich any elctromagnetic wave may fall or lie in like the bandwidth for visible light 400 nanometers to 700 nanometers

It depends on what you mean by size.  Photons are odd.  They have no measurable mass, yet do have energy, momemtum, and of course wavelength and frequency.  Photon interaction occurs in the very small scale, so you have to look to quantum physics as well.\n\nThere is no standard "size" of a photon, in terms that use our standard frames of reference.  You can try to approximate the location of a photon with Schrodinger's wave equation.  That gives a probability distribution.  Related to that is Heisenberg's uncertainty principle, which states that you can only know the combination of momentum or position of small "particles" to a maximum certainty.  If you know more about the momentum, you will know less about the position, and vice-versa.  There is a fundamental "quantum" effect going on here, in that space is not exactly continuous in this small scale (or for that matter, engergy, mass etc).\n\nIf you loosen the definition of "size" to mean something more like "heft", then you can think of high-energy photons (like gamma or cosmic rays) as being "bigger".  They have more momentum and energy, although the wavelength is shorter.\n\nIn summary I think that photons operate on such a quantum scale that I think "size" doesn't exactly correspond to our common notion of size.

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.

You can use the Rydberg formula, which relates the reciprocal of the wavelength of the photon absorbed or emitted to the squares of the reciprocals of the principal quantum numbers.\n\n1/wavelength = R(1/n_l^2 - 1/n_u^2)\n\nSo, for the listed values of n, \n\nA.  1/w = R(1/ 2^2 - 1/4^2) = 0.1875R\nB.  1/w = -0.75R\nC.  1/w = 0.21R\nD.  1/w = -0.04861R\n\nSince energy and frequency are proportional to 1/wavelength,\nlooks like the order is D, A, C, B.

the equation relating wave frequency and wave speed is (speed of the wave = frequency * wavelength), and simple algebra reveals that the wavelength varies directly with the speed of a wave, and inversely with the frequency.

Radiation in physics is a process of emission of energy or particles. Various forms of radiation may be distinguished, depending on the type of the emitted energy/matter, the type of the emission source, properties and purposes of the emission, etc.

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

frequency of a wave NEVER changes, whether you change the medium or the temperature of the medium. The speed changes and the wavelenght changes, but the frequency NEVER does.\n\nIf the temperature decreases, the speed of the wave decreases (due to decreased kinetic energy), so the wavelength decreases as well.
