Answer to Question #209900 in Physics for peaches

Question

Write the properties of EM waves (wavelength, frequency, speed)

Answer 1

Electromagnetic waves are transverse. In a vacuum, they propagate at the speed of light $(c=3\cdot 10^8\ m/s)$. In the environment $v=c/n$. The wavelength is related to the frequency by ratio

$\lambda=v/\nu$.
