Question: A. Rank these electromagnetic waves on the basis of their speed (in vacuum). B. Rank these electromagnetic waves on the basis of their wavelength. C. Rank these electromagnetic waves on the basis of their frequency. |
Solution:-
(A) Speed: All electromagnetic waves travel at the same speed in vacuum: Green Light = Infrared Light = FM Radio Wave = AM Radio Waves = X-ray= Yellow Light (B) From largest to smallest wavelength: AM Radio Wave > FM Radio Wave > Infrared Light > Yellow Light > Green Light > X-ray (C) From largest to smallest frequency: X-ray > Green Light > Yellow Light > Infrared Light > FM Radio Wave > AM Radio Wave |
