Question

2.6 formative 2
what pattern best describes the relationship between wavelength and frequency in the electromagnetic spectrum?
as wavelength increases, frequency decreases.
wavelength does not affect frequency.
as wavelength increases, frequency increases.
wavelength and frequency stay the same.

Explanation:

In the electromagnetic spectrum, the relationship between wavelength ($\lambda$) and frequency ($f$) is given by the formula $c = \lambda f$, where $c$ is the speed of light (a constant in a vacuum). Rearranging for $f$ gives $f=\frac{c}{\lambda}$. This shows an inverse - relationship. As wavelength increases, since the speed of light is constant, the frequency must decrease.

Answer:

As wavelength increases, frequency decreases.
