STANDARD Physics Wave Properties MCQ Question
Type: MCQ-numerical-Medium-Class 12
In the previous question, the frequency corresponding to the given part of electromagnetic wave is
A
5.4 × 10⁸ Hz
B
8.6 × 10⁷ Hz
C
3.2 × 10⁸ Hz
D
4.8 × 10⁷ Hz
Correct Answer
Option B
Detailed Explanation
The angular frequency ω = 5.4 × 10⁸ rad s⁻¹. The frequency ν is given by ν = ω/2π. Substituting the value of ω, we get ν = 5.4 × 10⁸ / 2π = 8.6 × 10⁷ Hz.
