The energy E of a photon and it’s wavelength is related by Eλ = X. The numerical value of X is? [h = 6.63 x 10^-34Js, C = 3 x 10^8 ms−¹]

A. 6.6 X 10-28
B. 1.99 X 10-27
C. 6.60 x 10-26
D. 1.99 x 10-25

Correct Answer:

Option D = 1.99 x 10-25

Explanation

E = HF = (hc)/λ
Eλ = hc
∴ X = hc ==6.63 x 10-34 x 108
= 1.989 x 10-25
=1.99 x 10-25
