Question

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 1Å would be(a) 2.5/5000 eV(b) 2.5 /(5000 )² eV(c) 2.5× 5000 eV(d) 2.5×(5000 )² eV

Answer 1

We know that E = hc/wavelength

here I shall take wavelength as v

E =hc/v

now as we know that energy is inversely proportional to wavelength so we can take that

E1 by E2 is equal to V1 by V2

applying this in the equation

we shall get 5000/1 = 2.5/x

(where x is the final energy )

so 5000/ 2.5 = 1/x

so x is equal to 2.5 / 5000

option (a )
