Chapter 4: Q10DQ (page 1072)

Most automobiles have vertical antennas for receiving radio broadcasts. Explain what this tells you about the direction of polarization of E in the radio waves used in broadcasting.

Short Answer

Expert verified

The direction of polarization of E in the radio waves used in broadcasting is in the vertical direction.

Step by step solution

01

Definition of Polarization.

The property of Polarization occurs when the oscillations of a wave have a definite direction relative to its propagation. A wave propagating in two directions is converted into one direction by polarizing it.

02

Deriving logical conclusion.

Since the automobile have vertical antennas for receiving radio broadcasts, the electromagnetic component of the transmission should be in the same plane as of the car antenna. Therefore the radio waves should be polarized in the vertical direction.

Most popular questions from this chapter

The power rating of a light bulb (such as a 100-W bulb) is the power it dissipates when connected across a 120-V potential difference. What is the resistance of (a) a 100-W bulb and (b) a 60-W bulb? (c) How much current does each bulb draw in normal use?

A 5.00-A current runs through a 12-gauge copper wire (diameter

2.05 mm) and through a light bulb. Copper has8.5脳108free electrons per

cubic meter. (a) How many electrons pass through the light bulb each

second? (b) What is the current density in the wire? (c) At what speed does

a typical electron pass by any given point in the wire? (d) If you were to use

wire of twice the diameter, which of the above answers would change?

Would they increase or decrease?

A fuse is a device designed to break a circuit, usually by melting when the current exceeds a certain value. What characteristics should the material of the fuse have?

Copper has 8.5脳1022free electrons per cubic meter. A 71.0-cm

length of 12-gauge copper wire that is 2.05 mm in diameter carries 4.85 A of

current. (a) How much time does it take for an electron to travel the length

of the wire? (b) Repeat part (a) for 6-gauge copper wire (diameter 4.12 mm)

of the same length that carries the same current. (c) Generally speaking,

how does changing the diameter of a wire that carries a given amount of

current affect the drift velocity of the electrons in the wire?

When is a 1.5 - VAAA battery not actually a 1.5 - V battery? That is, when do this its terminals provide a potential difference of less than 1.5 V ?
