JEE Advanced 2023 Physics question
The electric field associated with an electromagnetic wave propagating in a dielectric medium is given by V m. Which of the following option(s) is(are) correct? [Given: The speed of light in vacuum, m s]
Answer: (A),(D)
Solution
Wave speed m/s, so – (D) correct. For propagation along , : , (amplitudes) give $ = - =
