Question

42 an electromagnetic wave with a short wavelength has ______ than one with a long wavelength. more energy less frequency more frequency less energy skip 41/47 complete

Explanation:

The energy of an electromagnetic wave is directly proportional to its frequency and inversely proportional to its wavelength. The formula for the energy of a photon in an electromagnetic wave is $E = h
u$, where $E$ is energy, $h$ is Planck's constant, and $
u$ is frequency. Also, the relationship between frequency ($
u$) and wavelength ($\lambda$) is $
u=\frac{c}{\lambda}$, where $c$ is the speed of light. So, a shorter - wavelength wave has a higher frequency and more energy.

Answer:

A. more energy, C. more frequency
