NEET Physics Electromagnetic Waves MCQ Question
Type: MCQ-conceptual-Medium-Class 12
If μ₀ = permeability of free space & ε₀ = permittivity of free space. Find the value of μ₀ε₀.
A
1/9 × 10⁻¹⁶
B
9 × 10¹⁶
C
3 × 10⁸
D
1/3 × 10⁻⁸
Correct Answer
Option C
Detailed Explanation
The speed of light in vacuum is given by c = 1/√(μ₀ε₀). Therefore, μ₀ε₀ = 1/c² = 1/(3 × 10⁸)² = 1/9 × 10¹⁶.
