In the light of the above statements, choose the correct answer from the options given below.
[24feb2021shift1]
Both Statement I and Statement II are true
Statement I is false but Statement II is true

Solution:
Momentum of photon,
p
=
h
λ
Here,
h
=
Plank's constant,
λ
=
wavelength of light
Energy of photon
E
=
h
c
λ
If linear momentum are equal then wavelength also equal.
On decreasing wavelength, momentum and energy of photon increases.
