Chapter 31: Q. 22 (page 901)

A 1000W carbon-dioxide laser emits light with a wavelength of 10mm into a 3.0-mm-diameter laser beam. What force does the laser beam exert on a completely absorbing target?

Short Answer

Expert verified

Force,F=3.33路10-6N

Step by step solution

01

LASER

A laser's basis is built on three distinct elements: stimulated emission within an amplifying medium, population inversion of electronics, and an optical resonator.

02

Find force exerted by beam

The power is P=1000W. A simple formula can be used to calculate the force applied by the beam on the entirely absorbing target.

F=Pc,

where c=3.00路108m/sis the speed of light. Therefore

F=3.33路10-6N

An 80kgastronaut has gone outside his space capsule to do some repair work. Unfortunately, he forgot to lock his safety tether in place, and he has drifted 5.0maway from the capsule. Fortunately, he has a 1000Wportable laser with fresh batteries that will operate it for 1.0h. His only chance is to accelerate himself toward the space capsule by firing the laser in the opposite direction. He has a role="math" localid="1649937737036" 10-h supply of oxygen. How long will it take him to reach safety?

The intensity of sunlight reaching the earth is 1360W/m2. Assuming all the sunlight is absorbed, what is the radiation pressure force on the earth? Give your answer (a) in newtons and (b) as a fraction of the sun's gravitational force on the earth.

Large quantities of dust should have been left behind after the creation of the solar system. Larger dust particles, comparable in size to soot and sand grains, are common. They create shooting stars when they collide with the earth's atmosphere. But very small dust particles are conspicuously absent. Astronomers believe that the very small dust particles have been blown out of the solar system by the sun. By comparing the forces on dust particles, determine the diameter of the smallest dust particles that can remain in the solar system over long periods of time. Assume that the dust particles are spherical, black, and have a density of 2000kg/m3. The sun emits electromagnetic radiation with power 3.9脳1026W.
