Answer

Brief Explanations:

The infrared region of the electromagnetic spectrum has lower - frequency and longer - wavelength electromagnetic waves compared to the visible light region which human vision can detect. The relationship between frequency ($f$), wavelength ($\lambda$) and the speed of light ($c$) is $c = f\lambda$. Since $c$ is constant, when $f$ is lower, $\lambda$ is longer.

Answer:

a lower frequency and a longer wavelength.
