The energy of a photon of light is 3eV. Then the wavelength of photon must be

While working with light and X -rays, there is a useful relation between the energy of a photon in electron volts (eV) and the wavelength of the photon in angstom (A^(0)) .Suppose the wavelength of aphoton is lambdaA . Then energy of the photon is

The energy of a photon of light of wavelength 450 nm is

The energy of a photon of wavelength lambda is

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

What is the wavelength of a photon of energy 1 eV?

What is the wavelength of a photon of energy 1 eV?
