The diagram shows a cartoon of a sound wave produced while a student is speaking.

What happens to the sound wave when the student speaks louder?

• The amplitude increases

• the wavelength will double

• the speed will increase

• the amplitude will decrease

What type of waves might experience rarefaction?

• rope rays

• x-rays

• Sound Waves

• infrared rays

Which is the most likely explanation of how the students can hear and communicate using the objects?

• A Mechanical Wave transfers sound through the string

• sound bounces off the can and echoes

• sound travels through the string as an electromagnetic wave

• Transverse wave transfers sound through rope

As any type of wave travels through a medium, what is true about the particles in the medium?

• The particles of the medium move in a straight line and are carried with the wave.

• the particles of the medium move up and down and are carried with the wave.

• The particles of the medium are not carried along with the wave

• the particles of the medium move back and forth and are carried with the wave.

What kind of wave requires the particles of a medium to vibrate and transfer energy?

• infrared light wave

• Radio Wave

• Seismic Wave

• Visible light wave
