Question

An electromagnetic wave has a frequency of 500 MHz and a wavelength of 60 cm. (a) Calculate the speed of the wave. (b) Name the medium through which it is travelling.

KnowledgeBoat · Accepted Answer

(a) As we know, Velocity of wave (c) = frequency (f) x wavelength (λ) Given, f = 500 MHz Hence, f = 500 x 10⁶ Hz or f = 5 x 10⁸ Hz λ = 60 cm As 100 cm = 1m Therefore, 60 cm = m Hence, λ = 0.6 m Substituting the values in the formula above we get, Hence, Speed of the electromagnetic wave = 3 x 10⁸ ms^-1 (b) The electromagnetic wave is travelling through air.
