• They have a constant amplitude

• They can travel faster than the speed of light

• They only exist in a vacuum

What happens to the frequency of a wave as its wavelength decreases?

• The frequency remains constant

• The frequency becomes zero

• The frequency decreases

• The frequency increases

In the wave equation, what does 'c' represent?
