Chapter 16: Q. 27 (page 452)

What is the speed of sound in air (a) on a cold winter day in Minnesota when the temperature is –25°F, and (b) on a hot summer day in Death Valley when the temperature is 125°F?

Short Answer

Expert verified

Part a

The speed of sound in the air on a cold winter day in place M is 311m/s.

Part b

The speed of sound in the air on a hot summer day in place D is361m/s.

Step by step solution

01

Given information

The temperature on a cold winter day -25°F=241.48K

The temperature on a hot summer day is125°F=325K

02

Part a 

The speed of sound in the air on a cold winter day is

v=331m/s×241.48273=311m/s

Therefore, the speed of sound in the air on a cold winter day in place M is 311m/s.

03

Part b

The speed of sound in the air on a hot summer day is

v=331m/s×325273=361m/s

Therefore, the speed of sound in the air on a hot summer day in place D is361m/s.

Some modern optical devices are made with glass whose index of refraction changes with distance from the front surface. FIGURE CP16.84 shows the index of refraction as a function of the distance into a slab of glass of thickness L. The index of refraction increases linearly from n1 at the front surface to n2 at the rear surface. a. Find an expression for the time light takes to travel through this piece of glass. b. Evaluate your expression for a 1.0-cm-thick piece of glass for which n1 = 1.50 and n2 = 1.60.

A loudspeaker on a pole is radiating 100 W of sound energy in all directions. You are walking directly toward the speaker at 0.80 m/s. When you are 20 m away, what are (a) the sound intensity level and (b) the rate (dB/s) at which the sound intensity level is increasing? Hint: Use the chain rule and the relationship log10 x = ln x/ln 10.

A light wave has a 670 nm wavelength in air. Its wavelength in a transparent solid is 420 nm. a. What is the speed of light in this solid? b. What is the light’s frequency in the solid?

A wire is made by welding together two metals having different densities. FIGURE P16.59 shows a 2.00-m-long section of wire centered on the junction, but the wire extends much farther in both directions. The wire is placed under 2250 N tension, then a 1500 Hz wave with an amplitude of 3.00 mm is sent down the wire. How many wavelengths (complete cycles) of the wave are in this 2.00-m-long section of the wire?

String 1 in FIGURE P16.47 has linear density 2.0 g/m and string 2 has linear density 4.0 g/m. A student sends pulses in both directions by quickly pulling up on the knot, then releasing it. What should the string lengths L1 and L2 be if the pulses are to reach the ends of the strings simultaneously?
