JEE Main 2024 Physics question
If frequency of electromagnetic wave is 60 MHz and it travels in air along z direction then the corresponding electric and magnetic field vectors will be mutually perpendicular to each other and the wavelength of the wave (in m) is:
Answer: (D)
Solution
λ = c/f = 3 × 10⁸/(60 × 10⁶) = 5 m.
