Question

If wavelength of electromagnetic radiation is 5000A° then how much is the energy of radiation? ​

Answer 1

Explanation:

wavelength=lambda=5000A

E=hc/lambda

where,h=6.626×10^-34

c=3×10^8m/s

E=6.626×10^-34×3×10^8/5000

19.8×10^-26/5×10^3

3.96×10^-29

ans: 396×10^-27

hope it helps you my friend
