* High frequency means the light waves oscillate very rapidly, like a vibrating string. This is indeed associated with short wavelengths.

* Low frequency means the light waves oscillate more slowly. This is associated with long wavelengths.

Think of it like this:

* Imagine a wave in the ocean: A wave with a high frequency (lots of peaks and troughs per second) will have a short wavelength (the distance between two crests).

* A low frequency wave (fewer peaks and troughs per second) will have a long wavelength.

Important Point: Light travels at the speed of light, which is constant. So, the higher the frequency, the shorter the wavelength, and vice versa. This is a fundamental relationship in physics.

In summary: The statement is generally correct, but be careful to say "high frequency" rather than "very fast" because "fast" implies a speed, and the speed of light is constant.
