Question

ch9. q1
how are the frequency and wavelength of light related?
frequency equals wavelength divided by the speed of light.
they are directly proportional to each other.
wavelength is determined by dividing frequency by the speed of light.
they are inversely proportional to each other.

Explanation:

The relationship between frequency ($f$) and wavelength ($\lambda$) of light is given by the formula $c = f\lambda$, where $c$ is the speed of light (a constant). Rearranging this formula gives $f=\frac{c}{\lambda}$. This shows that as the wavelength increases, the frequency decreases and vice - versa.

Answer:

They are inversely proportional to each other.
