Question
The wavelength of a radio wave is 1500 m. The speed of radio waves is 3.0 × 10 8m / s. Calculate the frequency of the radio wave. Give the unit.
Solution
The frequency of a wave can be calculated using the formula:
Frequency (f) = Speed of light (c) / Wavelength (λ)
Given: Speed of light (c) = 3.0 × 10^8 m/s Wavelength (λ) = 1500 m
Substitute the given values into the formula:
f = (3.0 × 10^8 m/s) / 1500 m
Solving the above equation gives:
f = 2 × 10^5 Hz
So, the frequency of the radio wave is 2 × 10^5 Hz. The unit of frequency is Hertz (Hz).
