1. what is the relationship between the wavelength and frequency of a wave?

as the wavelength increases, the frequency decreases.
as the wavelength increases, the frequency increases.
as the wavelength decreases, the frequency remains the same.
as the wavelength decreases, the frequency decreases.

Explanation:

The relationship between wavelength ($\lambda$) and frequency ($
u$) of a wave is given by the equation $c = \lambda
u$, where $c$ is the speed of light (a constant). Rearranging for $
u$ gives $
u=\frac{c}{\lambda}$. This shows an inverse relationship. When $\lambda$ increases, $
u$ decreases (since $c$ is constant).

Answer:

As the wavelength increases, the frequency decreases.
