Answer:

0.2Hz

Explanation:

The wavelength of a radiowave can be calculated this;

λ = v/f

Where;

λ = Wavelength (m)

v = speed (m/s)

f = frequency (Hz)

Based on the information provided in this question, λ = 1.5 x 10^9 meters, c = 3 × 10^8m/s, f = ?

Hence, using λ = v/f

f = v/λ

f = 3 × 10^8 ÷ 1.5 x 10^9

f = 2 × 10^(8-9)

f = 2 × 10^-1

f = 0.2Hz
