The velocity of light in a medium depends on
- A electric and magnetic properties of the medium
- B electric properties of the medium only
- C magnetic properties of the medium only
- D the permittivity of free space only
Answer & Solution
Correct Answer
(A) electric and magnetic properties of the medium
Step-by-step Solution
Detailed explanation
The velocity of light \((v)\) in any given medium is determined by its permittivity \((\epsilon)\), which represents its electric property, and its permeability \((\mu)\), which represents its magnetic property. This relationship is defined by the following formula:…
