Question

2. When the light of frequency v or wavelength 2 interacts with one mole of reactants, the energy
absorbed (AE) is given as
a) I hy
c) hc/2, d) N/ho
b) Nhv​

Answer 1

Explanation:

We know that,

v=λ×υ.

E=hυ,p=h/λ

∴E/p=υ×λ=v.

The problem can also be approached by using dimensional analysis.
