Question

Calculate the wavelength of a photon having an energy of 2 electron volt?

Answer 1

E=h*new
new=c/lembda
now. lembda=(h*c)/E this will help you

Answer 2

Answer:

Explanation:

Energy of one Photon,e=hc/lambda

We have to find the value of lamba:

So,

Lambda=hc/e

=6.625×10^-34×3×10^8/2×1.6×10^-19

=6.204×10-7 m
