What is the wavelength of a 1.28 x 10^17 Hz wave?

The wavelength of the wave is 2.34 × 10⁻⁹ meters.

Given the data in the question;

Wavelength;

To determine the wavelength of the wave, we use the expression for the relations between wavelength, frequency and speed of light.

Where is wavelength, f is frequency and c is speed of light ( )

We substitute our values into the equation

Therefore, the wavelength of the wave is 2.34 × 10⁻⁹ meters.

The wavelength of the wave is 2.34 nm.

Explanation:

It is required to find the wavelength of a wave. A wave moves with a speed of light. Speed of a wave is given in terms of wavelength and frequency. So,

So, the wavelength of the wave is 2.34 nm.
