A radio station broadcast at a frequency of 600KHZ. If the speed of light in air is 3 × 10^8m/s¹. Calculate the wavelength of the radio wave

A. 2.20 × 10³m
B. 5.0 × 10²m
C. 5.0 × 10^5m
D. 11.8 × 1011¹¹m

Correct Answer:

Option B – 5.0 × 10²m

Explanation
V = f/λ

λ = v/f

= 3×10^8/600×10³ = 500m

= 5 × 10²m

N.B 600KHz Frequency = 600 × 10³Hz
