Answer to Question #209999 in Physics for erica

Question

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

Answer 1

Wavelength $\lambda$ is the distance between two successive crests or pikes: $\lambda=c/f.$

Frequency $f$ is how many oscillations a wave makes in a second: $f=c/\lambda.$

Speed $c$ defines how quickly a wave propagates in a medium: $c=f\lambda.$
