JEE Advanced 2026 Physics question
The electric field associated with an electromagnetic wave travelling in vacuum is given by , where ω is the angular frequency. All quantities are in SI units. The correct statement(s) about this wave is/are: [Given: speed of light in vacuum ms⁻¹.]
Answer: (A),(C)
Solution
A phase of the form describes a wave moving along ; here , so the wave moves along (A true) with m⁻¹ (B false). rad
