Chapter 33: Q4P (page 1001)

About how far apart must you hold your hands for them to be separated by 1.0nanolightsecond(the distance light travels in1.0ns)?

Short Answer

Expert verified

One nano light second is equal to 0.30m.

Step by step solution

01

Listing the given quantities

Velocity of light, c=3脳108m/s

Time periodt=1ns=1脳10-9sec

02

Understanding the concepts of velocity and distance

Using the velocity of light in air, we can find the distance traveled by the light in air in the given time.

Formula:

d=c脳t

03

Calculations of the distance traveled in the given time

d=c脳t=3脳108m/s脳1脳10-9s=0.30m

The distance traveled in the given time is 0.30m

Question: The average intensity of the solar radiation that strikes normally on a surface just outside Earth鈥檚 atmosphere is 1.4kw/m2.(a) What radiation pressure Pr is exerted on this surface, assuming complete absorption?(b) For comparison, find the ratio of Pr to Earth鈥檚 sea-level atmospheric pressure, which is1.0脳105鈥塒补

In Fig.33-38, a laser beam of power 4.60W and diameter d=2.60mm is directed upward at one circular face (of diameter d<2.60mm) of a perfectly reflecting cylinder. The cylinder is levitated because the upward radiation force matches the downward gravitational force. If the cylinder鈥檚 density is 1.20 g/cm3, what is its height H?

A plane electromagnetic wave traveling in the positive direction of anxaxis in vacuum has componentsEx=Ey=0andEz=(2.0V/m)cos[蟺脳1015s-1t-x/c]. (a) What is the amplitude of the magnetic field component? (b) Parallel to which axis does the magnetic field oscillate? (c) When the electric field component is in the positive direction of thezaxis at a certain pointP, what is the direction of the magnetic field component there?

Figure 33-28 shows the electric and magnetic fields of an electromagnetic wave at a certain instant. Is the wave traveling into the page or out of the page?

Radiation from the Sun reaching Earth (just outside the atmosphere) has an intensity of 1.4kW/m2. (a) Assuming that Earth (and its atmosphere) behaves like a flat disk perpendicular to the Sun鈥檚 rays and that all the incident energy is absorbed, calculate the force on Earth due to radiation pressure. (b) For comparison, calculate the force due to the Sun鈥檚 gravitational attraction.
