Answer: 1.58 x 10-17

The frequency of a wave is inversely proportional to its wavelength, meaning that as the wavelength increases, the frequency decreases and vice versa. We can use the following formula to calculate the frequency of a wave given its wavelength:

Frequency = Speed of light / Wavelength

Plugging in the values from the question, we get:

Frequency = 3 x 10^8 m/s / (4.75 x 10^-9 m)

= 1.58 x 10^-17 Hz

Therefore, the frequency of the wave is 1.58 x 10^-17 Hz.
