If the electric field in an EM wave in free space has a peak magnitude of 8.1×10−5V/m, what is the peak magnitude of the magnetic field strength? Express your answer using two significant figures.

2.7 * 10⁻¹³ T

Explanation:

The electromagnetic wave is produced when an oscillating electric and magnetic field interacts each other perpendicularly.

In an electromagnetic wave, the electric field peak magnitude E and the magnetic field peak magnitude B are related by

where ,

c = 3 * 10⁸m/s

E = 8.1×10−5V/m

the peak magnitude of the magnetic field:

2.7 * 10⁻¹³ T

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
