Students are modeling waves by shaking a rope up and down. We know this is a wave because–

Which of the waves is carrying the greatest amount of energy?

The waves that carry the most energy are the waves that–

The table below provides simplified data on the relationship between the amplitude of a wave and the energy the wave carries. Based on the pattern in the table, a wave with an amplitude of 4, would carry how much energy?

Which of the following waves has the highest frequency?

Which of the following provides an example of sound waves being reflected?

Automobile engineers create quieter cars and trucks by designing acoustic glass that–

A ringing bell makes noise inside a glass jar. Then the air is removed from the glass jar using a vacuum pump. When all of the air leaves the jar, the sound of the ringing bell can no longer be heard.

Which of the following best explains why the students can no longer hear the bell?

Geologists can learn about rock layers beneath the surface of the earth using sound waves. They use a vibration truck to send sound waves into the ground. A measuring truck has special microphones, called geophones that pick up sounds.

This method for learning about rock layers depends on what characteristic of sound waves?

Music studios use “soundproof” recording rooms. The walls of these rooms are designed in such a way that the only sounds that reach the microphones inside the room are sounds from inside the room. The most important characteristic in designing the soundproof room is to create walls that–
