Final Answer :
B
Explanation :
Frequency is defined as the number of complete wave cycles that occur in a given time period. It is measured in hertz (Hz), which is equal to one cycle per second. The equation c/λ relates the speed of light (c) to the wavelength (λ) of the electromagnetic wave. Since the speed of light is constant, the wavelength and frequency of the wave are inversely proportional to each other, i.e., frequency = c/λ. Therefore, B is the correct choice as it directly gives the frequency of the wave.
