Physics-Maxwell's Equations
NEET Physics Maxwell's Equations MCQ Question
Type: MCQ-numerical-Hard-Class 12
In Maxwell's equations, which mathematical relationship correctly represents the speed of electromagnetic waves in a vacuum?
A
c = 1 / sqrt(μ₀ε₀)
B
c = μ₀ / ε₀
C
c = 1 / (μ₀ε₀)
D
c = sqrt(μ₀ε₀)
Correct Answer
Option A
Detailed Explanation
The speed of light in a vacuum, c, is given by the equation c = 1 / sqrt(μ₀ε₀) as per Maxwell's equations, where μ₀ is the permeability and ε₀ is the permittivity of free space.
