Question

a photon have energy 50eV calculate frequency and wave length.​

Answer 1

Answer:

Energy=plank's constant* frequency

here energy(e)=50* 1.6*10^-19 joule

so frequency=energy/plank's constant

=50*1.6*10^-19/6.6*10^-34=12.1*10^15

wavelength=speed of light/frequency=3*10^8/12.1*10^15

=25*10^-9

Explanation:

hope it helps!!!!!
