Energy = Planks Constant x Frequency
Energy = 6.62607004 × 10∧-34 m2 kg / s x 6.0 x 10∧14 Hz
Energy ≈ 13.2 x 10∧-20 Joules.
Hope it helps.

Hey dear,
● Answer -
E = 3.96×10^-19 J
● Explanation -
# Given -
h = 6.6×10^-34 Js
υ = 6×10^14 Hz
# Solution -
Energy of a photon is given by -
E = hυ
E = 6.6×10^-34 × 6×10^14
E = 3.96×10^-19 J
Therefore, energy of a photon in light beam is 3.96×10^-19 J.
Hope this helps you.
