Answer :

What class is this for like subject?

The speed in a vacuum of red light that has a wavelength of 675 nanometers (nm) is 3 x 10⁸ m/s.

What is wavelength?

Wavelength is the distance between the adjacent crest or trough of the wave.

Wavelength gets increased or decreased depending upon the frequency. But speed of light in vacuum always remain constant irrespective of the value of wavelength of any light.

Thus, the speed in a vacuum of red light that has a wavelength of 675 nanometers (nm) is 3 x 10⁸ m/s.
