Light is an electromagnetic wave. Its speed in vacuum is given by the expression Options: A . &nbsp√μ0e0 B . &nbsp√μ0e0 C . &nbsp√e0μ0 D . &nbsp1√μ0e0

Answer: Option D : D μ 0 = 4 π × 10 − 7 , ϵ 0 = 8.85 × 10 − 12 N − m 2 C 2 so c = 1 √ μ 0 e 0 = 3 × 10 8 m e t e r s e c .

Question

Light is an electromagnetic wave. Its speed in vacuum is given by the expression

Options:

A . √μ0e0

B . √μ0e0

C . √e0μ0

D . 1√μ0e0

Answer: Option D
:
D

μ_{0} = 4 π \times 10^{- 7}, ϵ_{0} = 8.85 \times 10^{- 12} \frac{N - m^{2}}{C^{2}}

c = \frac{1}{\sqrt{μ_{0} e_{0}}} = 3 \times 10^{8} \frac{m e t e r}{s e c} .
