Name two types of perception of sound and the physical characteristics of sound waves that correspond to them.

Contrast the general physical state at room temperature and room pressure for ionic and molecular compounds.

What are the physical characteristics of sound waves?

The sound from a trumpet travels at 351 m/s in air. If the frequency of the note is 298 Hz, what is the wavelength of the sound wave? A. $9.93 \times 10^{-4} \mathrm{m}$ B. 0.849 m C. 1.18 m D. $1.05 \times 10^{5} \mathrm{m}$

Strike a tuning fork with a rubber hammer and hold it at arm’s length. Then press its handle against a desk, a door, a filing cabinet, and other objects. What do you hear? Why?

Find the frequency of a sound wave moving through iron at $25^{\circ} \mathrm{C}$ with a wavelength of 1.25 m.

A sound source plays middle C (262 Hz). How fast would the source have to go to raise the pitch to C sharp (271 Hz)? Use 343 m/s as the speed of sound.

A tuning fork produces three beats per second with a second, 392-Hz tuning fork. What is the frequency of the first tuning fork?

Why do various instruments sound different even when they play the same note?

One closed organ pipe has a length of 2.40 m. a. What is the frequency of the note played by this pipe? b. When a second pipe is played at the same time, a 1.40-Hz beat note is heard. By how much is the second pipe too long?

A weak pressure pulse Δp propagates through still air. Discuss the type of reflected pulse that occurs and the boundary conditions that must be satisfied when the wave strikes normal to, and is reflected from, (a) a solid wall and (b) a free liquid surface.

How does a spring pulse reflected from a rigid wall differ from the incident pulse?

Describe the relationship between the amplitude of a wave and the energy it carries.

What is the wavelength of a wave?
