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
Correct Answer: Option B
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
