Question

as frequency increases
energy increases and wavelength increases
energy decreases and wavelength increases
energy increases and wavelength decreases
energy decreases and wavelength decreases

Explanation:

The energy of a wave is directly proportional to its frequency ($E = hf$, where $E$ is energy, $h$ is Planck's constant, and $f$ is frequency), so as frequency increases, energy increases. The relationship between frequency ($f$) and wavelength ($\lambda$) is $c = f\lambda$ (where $c$ is the speed of light in a vacuum), so as frequency increases, wavelength decreases since the speed of light is constant.

Answer:

Energy increases and wavelength decreases
