Question

a photon has a. energy of 5×10^-11 erg its wavelength is​

Answer 1

Answer:

Given that, E =5 x 10-11 eV.

E = hC/ λ                                

where, h is the Planck constant, c is the speed of light in vacuum and λ is the photon s wavelength.

As h and c are both constants, the photon energy changes with direct relation to wavelength λ.

E = 1/ λ

or,  λ = 1/E = 1/5 x 10-11  =0.2 x 10-11 μm
