Chapter 31: Q. 7 (page 900)

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脳Bpoint out of the page.

b.) E脳Bpoints up.

A rocket cruises past a laboratory at 1.00x106m/sin the positive x-direction just as a proton is launched with velocity (in the laboratory frame) v=1.41x106i^+1.41x106j^m/s. What are the proton鈥檚 speed and its angle from the y-axis in (a) the laboratory frame and (b) the rocket frame?

The radar system at an airport broadcasts 11GHzmicrowaves with 150kW of power. An approaching airplane with a 31m2 cross section is 30Km away. Assume that the radar broadcasts uniformly in all directions and that the airplane scatters microwaves uniformly in all directions. What is the electric field strength of the microwave signal received back at the airport 200渭slater?
