Answer 2

The speed of electromagnetic wave in any matrial medium doesn't depend upon its intensity. hence option (c) is correct.

The speed of electromagnetic wave in any material medium doesn't depend upon its,

1. A) wavelength
2. B) frequency
3. C) intensity
4. D) permitivity

The speed of electromagnetic wave in any material medium is given by,

$v=\frac{1}{\sqrt{\mu\epsilon}}$

Where μ is permeability and ε is permitivity of given medium.

But we also know the electromagnetic wave is a wave and the speed of wave is the product of frequency and wavelength of that wave.

$v=\lambda\nu$

Where λ is wavelength and ν is frequency of the electromagnetic wave.

Hence, it is clear that speed of electromagnetic wave in any material medium depends upon

• frequency
• wavelength
• permitivity

Therefore the correct option is (C) intensity.
