In this problem, we have been given that there is a statement and we have to select whether this statement is right or not.
00:09
So the statement says that for a radio wave whose frequency is 1 ,000 kilohertz, its wavelength is 300 meters.
00:20
So to check whether the statement is right or not, let's use the wave equation according to which the wavelength times frequency, that should be the wave speed.
00:29
And since we are talking about the radio waves, they travel with a speed of three times 10 raise to 8 meter per second because this is an electromagnetic wave.
00:39
So we just multiply the wavelength and frequency to check whether we are getting the wave speed as three times 10 raise to 8 meter per second or not.
00:48
So when we multiply here, 1 ,000 into 1 ,000 because we are given the frequency in kilohertz and we have to convert this in hertz...
