Question

Calculate the wavelength of the radation whoes energy is 7.95×10 to the power - 19

Answer 1

Calculate the energy of a photon of radiation whose frequency is ... Solution 1. E=hf= 6.626×10−34J⋅s ×5.00×1014s−1 =3.31×10−19J.

Answer 2

Answer:

2.5×10^-7

Explanation:

energy of radiation=7.95×10^-19

wavelength=?

E=hc/λ ,

Now,

λ=hc/E

λ= 6.625×10^-34×3×10^8/ 7.95×10^-19

=6.625×10^-7/ 7.95

λ =2.5×10^-7 m
