The energy of a photon corresponding to the visible light of maximum wavelenth is approximately

What is the energy of a photon in eV corresponding to the vissible light of maximum wavelength?

Calculate the energies of photons corresponding to ultraviolet light and red light, given that their wavelengths are 3000overset@ A and 7000overset@ A respectively.(Remember that the photon are not coloured. Colour is human perception for that frequency range.)

The energy of photon for the maximum wavelength of visible light is approximately

The ratio of the energy of an X - ray photon of wavelength 1 Å to that of visible light of wavelength 5000 Å is

What is the ratio of the energy of an X ray photon of wavelength 1 Å to that of visible light of wavelength 5000 Å ?

The energy of a photon of red light (8000 A^@) is nearly

The energy of a photon of light with wavelength 5000 Å is approximately 2.5 eV . This way the energy of an X - ray photon with wavelength 1 Å would be
