Chapter 6: Q1DQ (page 1274)

In what ways do photons resemble other particles such as electrons? In what ways do they differ? Do photons have mass? Do they have electric charge? Can they be accelerated? What mechanical properties do they have?

Short Answer

Expert verified

Photons like other particles have momentum and scattering and have different mass, carry energy, acceleration and speed.

Step by step solution

01

Important Concepts

Properties of photons

02

Similarities  

Photons resemble other particles such as electrons in velocities, so they have a momentum like other particles. Moreover, photons like electrons in scattering.

03

Differences

鈥� Do photons have mass? Photons differ from electrons in mass; electrons have mass while photons have zero mass.

鈥� Photons travel with the speed of light while the other particles don't.

鈥� Do they have electric charge? Photons don't have any charges while electrons and other particles have.

鈥� Can they be accelerated? The acceleration of photons is zero because it travels with constant velocity.

鈥� What mechanical properties do they have? Photons have a linear momentum and carry energy while other particles don't

The black dots at the top of Fig. represent a series of high-speed photographs of an insect flying in a straight line from left to right (in the positive x-direction). Which of the graphs in Fig. most plausibly depicts this insect鈥檚 motion?

You are standing on a train platform watching a high-speed train pass by. A light inside one of the train cars is turned on and then a little later it is turned off. (a) Who can measure the proper time interval for the duration of the light: you or a passenger on the train? (b) Who can measure the proper length of the train car: you or a passenger on the train? (c) Who can measure the proper length of a sign attached to a post on the train platform: you or a passenger on the train? In each case explain your answer.

CP A beam of electrons is accelerated from rest and then passes through a pair of identical thin slits that are 1.25 nm

apart. You observe that the first double-slit interference dark fringe occurs at 18.0 from the original direction of the beam

when viewed on a distant screen. (a) Are these electrons relativistic? How do you know? (b) Through what potential difference were the electrons accelerated?

During the photoelectric effect, light knocks electrons outof metals. So why don鈥檛 the metals in your home lose their electrons when you turn on the lights?

Why Are We Bombarded by Muons? Muons are unstable subatomic particles that decay to electrons with a mean lifetime of 2.2渭s. They are produced when cosmic rays bombard the upper atmosphere about km above the earth's surface, and they travel very close to the speed of light. The problem we want to address is why we see any of them at the earth's surface. (a) What is the greatest distance a muon could travel during its 2.2渭蝉lifetime? (b) According to your answer in part (a), it would seem that muons could never make it to the ground. But the 2.2-碌s lifetime is measured in the frame of the muon, and muons are moving very fast. At a speed of 0.999c, what is the mean lifetime of a muon as measured by an observer at rest on the earth? How far would the muon travel in this time? Does this result explain why we find muons in cosmic rays? (c) From the point of view of the muon, it still lives for only 2.2渭s, so how does it make it to the ground? What is the thickness of the 10 km of atmosphere through which the muon must travel, as measured by the muon? Is it now clear how the muon is able to reach the ground?
