Answer: 5m
Explanation:
Given that:
Wavelength (λ)= ?
Frequency of wave (F) = 60MHz
[If 1 MHz = 1,000,000 Hz
60MHz = 60 x 1,000,000 = 6 x 10^7Hz]
Speed of wave (V) = 3 x 10^8 m/s
The wavelength is the distance covered by the wave in one complete cycle. It is measured in metres, and represented by the symbol λ.
So, apply the formula V = F λ
Make λ the subject formula
λ = V/ F
λ = 3 x 10^8 m/s / 6 x 10^7Hz
λ = 5m
Thus, the wavelength of an electromagnetic wave is 5 metres.
