A 20% Part (d) What is the wavelength of the electromagnetic wave. 1. in terms of o and the speed of light c? A 20% Part (e) Calculate the wavelength 1 in meters.

Answer 1

a). Eo = Bo * c

b)

Eo = 2.5* 10^-6* 3* 10^8

Eo = 750 N/C

c)

f = w/ ( 2 pi)

d)

L = c/f = 2 pi c/ w

e)

L = 2pi * 3* 10^8/ (7.5* 10^7)

L = 25.12 m
