In what directions are the electromagnetic waves traveling in FIGURE

Short Answer

Expert verified

(a) Electromagnetic wave points travelling out of the page

(b) Electromagnetic wave points travelling upwards

Step by step solution

01

electromagnetic waves

Electromagnetic waves, or EM waves, are waves that are created whenever an electric field and a magnetic field move together. EM waves, in other words, are composed of alternating magnetoelectric fields.

02

Graph to explain (part a and b)

a.) The right-hand rule has E×Bpoint out of the page.

b.) E×Bpoints up.
