1.	An electromagnetic wave has a frequency of 500 MHz and a wavelength of 60 cm.(a) Calculate the velocity of the wave.(b) name the medium through which it is travelling
Answer» (a) Frequency = 500MHz = 500 x 10⁶Hz Wavelength = 60 cm = 0.6 m Velocity of wave = frequency x wavelength = 500x 10⁶ x 0.6 = 3 x 10⁸m/s (b) Electromagnetic wave is travelling through air.

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

Answer»

(a) Frequency = 500MHz = 500 x 10⁶Hz

Wavelength = 60 cm = 0.6 m

Velocity of wave = frequency x wavelength

= 500x 10⁶ x 0.6 = 3 x 10⁸m/s

(b) Electromagnetic wave is travelling through air.
