NEET Physics (general) MCQ Question
Type: MCQ-fact-Medium-Class 12
What is the energy of a photon produced by a laser with a frequency of 6.0 × 10^14 Hz?
A
98 × 10^-19 J
B
24 × 10^-6 J
C
07 × 10^-19 J
D
6.63 × 10^-34 J
Correct Answer
Option A
Detailed Explanation
The energy of a photon can be calculated using E = h * n. For the given frequency, substituting the values yields E = (6.63 × 10^-34 J s)(6.0 × 10^14 Hz) = 3.98 × 10^-19 J.
