Making Observations Describe how you interact with waves during a typical school day. Document the types of waves you encounter. Document also how often you interact with each type of wave. Decide whether some types of waves are more important in your life than others.

Ocean waves are hitting a beach at a rate of 2.0 Hz. The distance between wave crests is 1.5 m. Calculate the speed of the waves.

A piano tuner hears a beat every 2.00 s when listening to a 264.0-Hz tuning fork and a single piano string. What are the two possible frequencies of the string?

Evaluating Information A new car is advertised as having antinoise technology. The manufacturer claims that inside the car any sounds are negated. Evaluate the possibility of such a claim. What would have to be created to cause destructive interference with any sound in the car? Do you believe that the manufacturer's claim is correct?

Find the domain of the function $f ( x ) = \frac { x ^ { 2 } - 1 } { x ^ { 2 } + 3 x - 4 }$

A piano tuner uses a 512-Hz tuning fork to tune a piano. He strikes the fork and hits a key on the piano and hears a beat frequency of 5 Hz. He tightens the string of the piano, and repeats the procedure. Once again he hears a beat frequency of 5 Hz. What happened?

Describe the changes in elastic potential energy and kinetic energy that occur when a mass vibrates on a spring.

The frequency of radio wave range from about $3.00 \times 10^{5} \mathrm{Hz} \text { to } 3.00 \times 10^{7} \mathrm{Hz}$. What is the range of wavelengths of these waves? Use $3.00 \times 10^{8} \mathrm{m} / \mathrm{s}$ as the speed of electromagnetic waves.

Name the conditions required for two waves to interfere constructively.

Use the kinetic theory to explain the difference in wave speed in solids, liquids, and gases.

Root Words The word reflection contains the root fled . Use a dictionary to find the origin and meaning of this root, and explain why it is appropriate that the word reflection contains this root. Then, list at least three other words that contain the root.

Draw a picture of a standing wave, and label a node and an antinode.
