Question on: JAMB Physics - 2017
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
A
2.20 × 10\(^3\)m
B
5.0 × 10\(^2\)m
C
5.0 × 10\(^5\)m
D
11.8 × 10\(^{11}\)m
Ask EduPadi AI for a detailed answer
Correct Option: B
V = fλ
λ = (\frac{v}{f})
= (\frac{3 \times 10^8}{600 \times 10^3}) = 500m
= 5 × 102m
N.B 600KHz Frequency = 600 × 103Hz
