The names for the top and bottom points of a transverse wave. ANSWER

Crest and trough Unit Review Jeopardy

The time it takes for one cycle to occur. Answer

period Back to JeopardyJeopardy

A single unit of periodic motion Answer

cycle Back to JeopardyJeopardy

Distance from the crest of one wave to the crest of the next Answer

wavelength Back to JeopardytoJeopardy

Unit of measurement for frequency Answer

Hertz (Hz) Back to JeopardyJeopardy

This happens when two or more waves interact Answer

Back to JeopardyJeopardy 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 Answer

Destructive interference Back to Jeopardy

Occurs when two waves interact to form a bigger wave Answer

Constructive Interference Back to Jeopardy

The type of wave that travels in the same direction as the oscillations Answer

longitudinal Back to Jeopardy

Give an example of a transverse Wave Answer

Ocean waves, electromagnetic waves Back to JeopardyJeopardy

Give an example of a longitudinal wave Answer

Sound waves Back to JeopardyJeopardy

When a door is only slightly opened, sound will pass from one room to another due to mainly _________________. Answer

diffraction Back to JeopardyJeopardy

What occurs when sound waves hit an acoustic tile in an auditorium? Answer

absorption Back to JeopardyJeopardy

5 meters Back to JeopardyJeopardy

DAILY DOUBLE!!!! QUESTION

Give the units for the variables used in v= f

V= m/s = m f = hertz Back to JeopardyJeopardy

The unit for measuring the loudness of sound AnswAnswer

Decibel (dB) Back toUnit Review JeopardyUnit Review Jeopardy

True or False: The speed of sound is about 343 m/s Answer

True Back to JeopardyJeopardy

True or False: Sound waves are slower than light waves Answer

True Back to JeopardyJeopardy

True or False: Sound waves travel faster in outer space than in air. Answer

False Sound 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 JeopardyJeopardy

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. Back to JeopardyJeopardy (slowest)Air, water, wood (fastest)

As you decrease the temperature & pressure of air, does the speed of sound increase or decrease? Answer

Decreases! Back to JeopardyJeopardy

As the wavelength decreases, the frequency of a wave ________________ Answer

increases Back to JeopardyJeopardy

As the loudness of a sound increases, the amplitude of the wave ______________ Answer

increases Back to JeopardyJeopardy

The frequency increases when the source and the observer approach each other and decreases when they move apart. Answer

The Doppler Effect Back to JeopardyJeopardy

Which of the following sounds has the shortest wavelength? A)Thunder @ 75 hz B) a female soprano singer @2000 hz C) a man’s voice @ 500 hz Answer

B) a female soprano singer @2000 hz Back to JeopardyJeopardy

What is the equation you would use to solve for wavelength of a wave? Answer

 Back to JeopardyJeopardy V / f =

A wave made by dropping a ball in water has a frequency of 2 Hz and a speed of 10 m/s. What is the wavelength of this wave? Answer

5 m Back to JeopardyJeopardy

A tuning fork has a frequency of 200 hz and the wavelength of sound produced is 10m. Calculate the velocity of the wave. Answer

2000 m/s Back to JeopardyJeopardy

An ocean wave is moving toward the shore with a velocity of 15m/s. If its frequency is 5hz, what is the wavelegth? Answer

3 m Back to Jeopardy

A rope is moved with a speed of 120 m/s. If the length of the wave is 10 m, what is the frequency of the wave? Answer

12 hz Back to Unit Review JeopardyJeopardy
