Which of the following statements is not true with respect to electromagnetic waves? |
They can be polarised They carry energy and momentum They travel with speed given by $v = \sqrt{μ_oε_o}$ in vacuum They do not require material medium to propagate |
They travel with speed given by $v = \sqrt{μ_oε_o}$ in vacuum |
The correct answer is Option (3) → They travel with speed given by $v = \sqrt{μ_oε_o}$ in vacuum The speed of an electromagnetic wave - $v=\frac{1}{\sqrt{μ_oε_o}}$ |
