Answer:
0.05 meters
Explanation:
Given that:
Frequency of wave = 6 x 109Hz
Assume the wave travels at the speed of light, V = 3 * 10^8 m/s
The wavelength is related to frequency and speed of wave using the relation ;
v = fλ
λ = speed of wave, V / frequency, f
λ = (3 * 10^8) / (6 * 10^9)
λ = 0.5 * 10^(8 - 9)
λ = 0.5 * 10^-1
λ = 0.05 m = 5cm
