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

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

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

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

19. 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.

20. 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

21. 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

22. 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

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

24. 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

25. 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

26. 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
