Module 7.2: Wave Properties

Given: The electric field of a plane electromagnetic wave traveling in air exhibits the pattern shown in the figure. In order to be able to visually observe the time variation, the rate has been slowed down by a factor M.

	Q1.	What is the wavelength of the wave?
	=	cm
	Q2.	What is the apparent frquency of the wave?
	f=	Hz
	Q3.	What is the slow-down factor, M = (True frequency / Apparent frequency)?
	M=	X109
