A radio station broadcast at a frequency of 600KHZ. If the speed of light in air is 3 × 108ms−1. Calculate the wavelength of the radio wave
Answer Details
The formula to calculate the wavelength of a wave is:
wavelength = speed of light / frequency
where wavelength is the distance between two consecutive peaks or troughs of a wave, frequency is the number of cycles of the wave per second, and the speed of light in air is approximately 3 × 10^8 m/s.
In this question, the frequency of the radio wave is given as 600 kHz, which means that it has 600,000 cycles per second. Substituting these values into the formula, we get:
wavelength = 3 × 10^8 m/s / 600,000 s^-1
wavelength = 500 m
Therefore, the wavelength of the radio wave is 500 meters.
The answer is: 5.0 × 10^2 m.
