The speed of light (c) is approximately 3.0 x 10^8 meters per second. The frequency (f) of a wave is related to its wavelength (λ) and the speed of light by the equation:
f = c / λ
Substituting the given values:
f = (3.0 x 10^8 m/s) / (10 m) = 3.0 x 10^7 Hz
So, the correct answer is B. 3.0 x 10^7 Hz.
