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
2.20 × 10\(^3\)m
5.0 × 10\(^2\)m
5.0 × 10\(^5\)m
11.8 × 10\(^{11}\)m
Explanation
V = fλ
λ = \(\frac{v}{f}\)
= \(\frac{3 \times 10^8}{600 \times 10^3}\) = 500m
= 5 × 102m
N.B 600KHz Frequency = 600 × 103Hz
λ = \(\frac{v}{f}\)
= \(\frac{3 \times 10^8}{600 \times 10^3}\) = 500m
= 5 × 102m
N.B 600KHz Frequency = 600 × 103Hz
