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
