NEET Chemistry Orbitals MCQ Question

Type: MCQ-numerical-Medium-Class 11

Calculate the energy of a photon corresponding to a wavelength of 0.50 Å.

A

97 × 10^-15 J

B

00 × 10^-16 J

C

48 × 10^-18 J

D

5.00 × 10^-17 J

Correct Answer

Option A

Detailed Explanation

The energy of a photon (E) is given by E = hc/λ, where h is Planck's constant and c is the speed of light. Using λ = 0.50 Å = 0.50 × 10^-10 m, E = (6.626 × 10^-34 Js)(3 × 10^8 m/s) / (0.50 × 10^-10 m) ≈ 3.97 × 10^-15 J.
