To understand the formula representing a traveling electromagnetic wave.

Light, radiant heat (infrared radiation), X rays, and radio waves are all examples of traveling electromagnetic waves. Electromagnetic waves comprise combinations of electric and magnetic fields that are mutually compatible in the sense that the changes in one generate the other.

The simplest form of a traveling electromagnetic wave is a plane wave. For a wave traveling in the x direction whose electric field is in the y direction, the electric and magnetic fields are given by

E⃗ =E0sin(kx−ωt)j^,

B⃗ =B0sin(kx−ωt)k^.

This wave is linearly polarized in the y direction.

Part F

What is the wavelength λ of the wave described in the problem introduction?

Express the wavelength in terms of the other given variables and constants like π.

Part G

What is the period T of the wave described in the problem introduction?

Express the period of this wave in terms of ω and any constants.

Part H

What is the velocity v of the wave described in the problem introduction?

Express the velocity in terms of quantities given in the introduction (such as ω and k) and any useful constants.
