[" The energy of a photon of wavelength "4000A" is "],[[" use "h=6.66times10^(-34)Js]]

The energy of a photon of wavelength 4000 Å is (use h=6.66xx10^(-34) J-s)

The energy of photon of reddish light having wavelength 660nm is ( h=6.6xx10^(-34)Js )

Calculate the energy of a radiation having a wavelength of '4000 A (h=6.6 xx 10^(-34)) J s)'

Which has a higher energy, a photon of violet light with wavelength 4000Ã… or a photon of red light with wavelength 7000Ã…? [ h=6.62xx10^(-34)Js ]

Find the photon energy for electromagnetic waves of wavelength 20m. Given h= 6.63xx10^(-34) "Js".
