The energy increases as the frequency increases. The frequency decreases as the wavelength increases. So, the energy decreases as the wavelength increases.

The energy of a photon is described by the equation: Where l is the wavelength, h is Planck's constant, c is the speed of light, and E is the energy. So, the energy of a photon increases as the wavelength decreases.

Remember that for any wave, wavelength x frequency = speed (of the wave). So, as the wavelength increases, the frequency decreases. Also, since the energy of a photon is proportional to the frequency, the energy will decrease as well in this case.

Type your answer here... radiation electromagnetic wave (or light) is in the form of photon. when this photon strikes the material it increases kinetic energy of particles of the material. that is thermal energy or heat
