Chapter 33: Q9P (page 1001)

Some neodymium–glass lasers can provide100TWof power in1.0nspulses at a wavelength of0.26μm. How much energy is contained in a single pulse?

Short Answer

Expert verified

Energy contained in a single pulse is 1.0×105J.

Step by step solution

01

Determine the given quantities

Laser power is:

P=100TW=100×1012W

Pulse time is:

t=1.0ns=1.0×10-9s

02

Determine the concepts of energy and power

The energy depends on power and time.

E=Pt

03

Determine the energy contained in a single pulse

The energy and power are related as

E=Pt

Substitute the values and solve as:

E=100×1012×1.0×10-9=1.0×105J

Energy contained in a single pulse is 1.0×105J.

A square, perfectly reflecting surface is oriented in space to be perpendicular to the light rays from the Sun. The surface has anedge lengthof l=2.0 mandislocatedr=3.0×1011 mfromthe Sun’s center. What is the radiation force on the surface from the light rays?

In Fig. 33-48a, a light ray in water is incident at an angleθ1on a boundary with an underlying material, into which some of the light refracts. There are two choices of the underlying material.
