The visible part of the electromagnetic spectrum consists of the colors that we see in a rainbow. Different colors correspond to different wavelengths of light. Which color of visible light has the shortest wavelength? A. red C. violet B. green D. yellow C. VIolet Category

Which carries more energy, a wave with a short wavelength or
a wave with a long wavelength? A wave with a short wavelength

What is the name given to the lowest point of a wave?
A. crest C. amplitude B. Trough D. rest position B. trough

What kind of wave forms when the vibrating particles move perpendicularly to the direction the wave is going? A transverse wave

Radiant energy is the source of electromagnetic waves, which include X-ray, infrared, and ultraviolet waves among others. The diagram below shows the electromagnetic spectrum. Which of these statements best describes the speed of these waves in a vacuum? A. X-rays travel slower than infrared. B. Infrared travels slower than X-rays. C. Infrared travels faster than ultraviolet. D. Infrared travels at the same speed as X-rays. D. Infrared travels at the same speed as X-ray

Which of these waves do NOT require a medium? a. ocean waves

What forms can a medium be in?
Solid, Liquid, or Gas

The diagram below shows a sound wave traveling
The diagram below shows a sound wave traveling. What happens to the particles of the medium as a part of the wave moves from point N to point M? A. The particles grow larger and then smaller. B. The particles move from point N to point M. C. The particles move from point M to point N. D. The particles move together and then apart again. D. The particles move together and then apart again

If a wave is traveling at a certain speed and its frequency is doubled, what happens to the wavelength of that wave? a. It doubles. b. It is halved. c. It is stopped. d. It remains the same. B. it is halved

Any disturbance that transmits energy is called a __________
A wave

Which of the following types of waves requires a medium?
a. visible light b. X rays c. microwaves d. sound waves d. Sound waves

A section of a longitudinal wave where the particles are crowded together is called a
a. rarefaction. b. compression. c. vibration. d. surface wave b. compression

Which direction did the waves move? a. away from Celine
Celine threw a pebble into the center of a small pond. The splash of the pebble created several waves. Which direction did the waves move? a. away from Celine b. toward Celine c. in all directions away from the splash d. up and down around the splash c. In all directions away from the splash

Explain how mechanical and electromagnetic waves are different.
Mechanical waves need a medium to travel and electromagnetic waves do not

What unit is used to describe the frequency of a wave? a. decibel
b. hertz c. meters per second d. wavelength b. hertz

The number of waves produced in a given amount of time is called ___________
frequency

Explosions are constantly happening on the surface of the sun, but we never hear them on Earth. Explain why the explosions cannot be heard Sound waves are mechanical waves, which must travel through a medium. Because no matter exists in outer space, sounds cannot reach Earth from the sun.

When you strike a drum hard, the sound wave produced has a larger amplitude than a sound wave produced when you tap lightly on the same drum has. Predict how a sound wave that has a large amplitude will compare to a sound wave that has a small amplitude. a. the large-amplitude sound wave will be softer b. the large-amplitude sound wave will be louder c. the large-amplitude sound wave will have a higher pitch d. the large-amplitude sound wave will have a lower pitch b. The large- amplitude sound wave will be louder

During a thunderstorm, Sanjay saw lightning and then heard thunder 5 s later. What would be different if the air had been warmer? He would have seen the lightning and heard the thunder at the same time. He would have heard the thunder before seeing the lightning. He would have heard the thunder sooner. D. He would have heard the thunder later D. He would have heard the thunder later

What happens to the speed of a sound wave as it
passes from the air into the ground? A. it decreases B. it increases C. it remains constant D. it immediately stops B. it increases

Multiplying the wavelength of a wave by the frequency of the wave gives the _________ of the wave.
Wave speed

How does a wave transfer energy without transferring matter?
Most waves transfer energy by the vibration of particles in a medium. The energy is passed from one particle to a particle next to it, causing each particle to vibrate like the first particle. The vibration creates only a transfer of energy—it does not transfer any of the matter or the medium

Why do sound waves travel around corners better than light waves?
a. Sound waves radiate. b. Light waves have long wavelengths. c. Sound waves have long wavelengths. d. Light waves radiate. C. Sound waves have long wavelengths

Why does a wave with a large Amplitude carry more energy than a
Wave with a small amplitude? The amplitude of the wave is related to its height. Because it takes more energy to move the particles of the medium further from their rest position in a wave with a large amplitude, the wave carries more energy
