Question

an electromagnetic wave has a frequency of 500 mhz and a wavelength of 60 cm. calculate the velocity of the wave and name the medium through which it is travelling

Answer 1

Velocity[v] = frequency[f]  X  wavelength[ lamda unit of wavelength ]

v = 500 X10 power 4 X60
   = 30000 X 10 power 4
   = 3 X 10 power 8 m/s
