Waves with a short wavelength have the most energy. Red waves have a relatively long wavelength (in the 700 nm range), and violet waves are much shorter – roughly half that. Because violet waves have the shortest wavelength of the visible light spectrum, they carry the most energy.

The energy of a 500 nm photon is 4 x 10^-19 J.

Explanation: To find energy, you must know the frequency of the light. Since we are given wavelength we can use this equation: c= λ v where c is the speed of light (3 x 108 m/s), λ is the wavelength, and the v is the frequency (units: 1/s).

which has higher energy a photon of red light with wavelenght 7500 A or a photon of green light with wavelenght 5250 A? Thus red light with greater wavelength has lower energy than green light.

The energy of a photon depends on its wavelength: longer wavelength photons have less energy and shorter wavelength photons have more. Red photons, for example, have less energy than blue ones. Until about 1900, scientists only understood electromagnetic radiation to be made up of waves.

The amount of energy is directly proportional to the photon’s electromagnetic frequency and thus, equivalently, is inversely proportional to the wavelength. The higher the photon’s frequency, the higher its energy. Equivalently, the longer the photon’s wavelength, the lower its energy.

The one photon having larger wavelength will have less energy because E= h/wavelength. Thus violet light photon will have more energy.

Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation.

Violet light has greater frequency than green light hence it will have greater energy.

Blue light has a shorter wavelength than green light. Thus, blue light has more energy per photon than green light does. As a result, the electrons ejected by the blue light should have the higher kinetic energy.

Calculate the energy of one photon of violet light. b.i.E = hυ E = (6.626×10-34J*s)( 7.32x1014Hz) = 4.85×10-19 J c.

Answer. Thus red light with greater wavelength has lower energy than green light.

Ultraviolet radiation carries more energy and infrared radiation less energy than visible light. All radiation from the sun with a wavelength below 290 nm, that is most high-energy UV-radiation, is filtered out by the atmosphere before reaching the Earth’s surface.

Violet light has a wavelength of ~400 nm, and a frequency of ~7.5*1014 Hz.

The different types of radiation are defined by the the amount of energy found in the photons. Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays.

So, higher the frequency, higher the energy. Hence, green light has more energy than red light.
