Interference
The type of wave that oscillates perpendicular to the
direction the wave travels.
Answer
transverse
Back to Jeopardy
Occurs when two waves interact with each other to make a wave of smaller
amplitude

True or False: The speed of sound is about 343 m/s
Answer
True
Back to Jeopardy
True or False: Sound waves are slower than light waves
Answer
True
Back to Jeopardy
True or False: Sound waves travel faster in outer space than in air.
Answer
FalseSound depends on three things: a vibrating source to create the sound waves, a medium (such as air) to carry the waves, and a receiver to hear them. Sound waves can't travel through a
vacuum.
Back to Jeopardy
Give the correct order from slowest to fastest for the
speed of sound through these three media.
[water, air, wood]
Answer
Some mediums are better at conducting sound than others. Like all gasses, air is a poor medium for sound waves. Liquids, such as water, are better, and rigid, solid substances, such as iron and stone, are even better, while rubber, cork, and cotton are some examples of poor
conductors.

As you decrease the temperature & pressure of air,
does the speed of sound increase or decrease?
Answer
Decreases!
Back to Jeopardy
As the wavelength decreases, the frequency of a wave
________________
Answer
increases
Back to Jeopardy
As the loudness of a sound increases, the amplitude of the wave ______________
Answer
increases
Back to Jeopardy
The frequency increases when the source and the observer approach each other and decreases when they move apart.
Answer
