Which of these waves CANNOT travel through the vacuum of space?

Sound waves are transferred by the compression of particles. The closer the particles are to one another, the faster the energy is transferred. Therefore, sound energy directly depends upon the _________ of the medium.

While watching a recent science fiction movie, one Klingon spaceship blows up a Droid spaceship with a laser gun. The Klingon crew watches out the port window and covers their ears to muffle the noise from the explosion. Scientifically, this scene is inaccurate because

Refraction or the bending of waves takes place when a light wave changes

Identify the characteristic of a transverse wave that doubled from wave A to wave B.

Sound waves travel fastest through a

The hammering on a train track is often heard twice by workers farther down the track; first as the sound travels through the steel and second as the sound travels through the air. This suggests which graph is true?

Letter D represents the __________ of the wave.

Comparing Wave A (black) to Wave B (green), Wave A has a

Which waves can travel through a vacuum?

All waves transmit energy. Only one type of wave does not require a medium to transmit energy. That is a(n) _________ wave.

The speed of sound waves through two different media, steel and air, was recorded. According to the graph, sound waves travel

Using an oscilloscope, it can be observed that the pitch of a sound is directly related to a sound wave’s frequency while the volume is directly related to a sound wave’s amplitude. The change shown in the illustration suggests that the

Volume or intensity of a sound wave is measured by the size of the _________ and reported in decibels.

In this wave, there is a vertical line which represents what part of the wave?

Based on the data, which statement BEST describes sound?

According to the data, which sound is MOST intense?

Maria and Sarah made a set of paper cup telephones. First the girls punched a hole in the bottom of each cup. Then they connected the cups with a very long piece of string, knotted in the bottom of each cup. Maria went down the hall to her bedroom while Sarah stayed in the kitchen. When Maria put the cup to her ear she could hear Sarah talking to her because.

Sound energy and loudness are functions of wave _______________. Amplifiers increase sound energy and decibel level or loudness so sounds can be heard at greater distances.

To allow a speaker's voice to be heard in an auditorium, an amplifier was used to increase the sound energy (loudness) of the wave seen in the image above the answer choices. Which wave is the result of amplification and produces a louder sound?

How do sound waves move in air?

By now, you know that sound is produced by vibrations. These vibrations can travel through solids, liquids, and gases, but not through ______________.

_________ is the slight bending of light as it passes around the edge of an object.

Compression or sound waves behave a lot like transverse or electromagnetic waves. Compression waves exhibit ALL BUT one of the following behaviors. That is

What statement explains the changes from wave A to wave B?

Sound travels in waves. Sound waves cannot travel through

The crowd in a stadium creates a wave traveling across the stands by having people stand up and then sit down one after another. The people move up and down creating the appearance of a wave moving across the stadium. This type of wave is best described as

Sound waves that start in air can move into water. This is because it is __________ that is transferred and not_____________ .

Based on the images seen here, identify which phase of matter would transmit sound waves the fastest, and why?

In the old west, a cowboy would put their ear on the railroad track to determine if a train was coming. Using this method, they could tell if the train was coming sooner than just listening for the train. A good explanation for this would be that

A student observes that it is hard to hear music underwater in a pool. They state that the sound is always muffled. They conclude that the speed of sound in water must be slower than in air. What would you say about the validity of this conclusion?
