What can you conclude about red visible light waves compared to blue visible light waves?

Here are the choices for this question.

Blue visible light waves have a lower frequency than red visible light waves.

Blue visible light waves have the same wavelength as red visible light waves.

Blue visible light waves have a higher frequency than red visible light waves.

--->Blue visible light waves have a greater wavelength than red visible light waves.

The energy of red light is low, it has shorter wavelength. The blue light has a high energy relative to red light. The blue light then has longer wavelengths.
