Wave at Jeopardy Sounds goodProperties of Waves In real lifeMix it upWave phenomena

The reason you can’t hear sound while in a vacuum It needs a medium

The speed of sound will change if you change its: Medium A.Medium B.Amplitude C.Loudness

When I crank up the volume on my radio I’m not only changing how loud my radio is, I’m also changing a sound wave’s Amplitude

The units of frequency Hertz (Hz)

Like vibrating wine glasses, an object that is vibrating at its natural frequency is experiencing: Resonance

The property of waves highlighted in this figure Amplitude

Which of the following waves has the highest frequency? A

Through which of the following media does sound travel faster? a)Air b)A Brick wall c)Outer space b

The direction in which particles move on a longitudinal wave b a) particle wave particle wave b)c) particle wave particle wave d)

A secondary earthquake wave looks like this: Up and down In what direction would you move if the wave is moving toward you?

Rock idol Mr. Marrero plays a low pitch note on a guitar followed by a high pitch note. What property of waves is he changing? Frequency

Which property of waves are you experiencing when a someone drives by you in a car with a song that has a very low bass that makes your chest vibrate at its natural frequency Resonance

The type of wave done by fans on a sports event. Transverse wave

The units in which wavelength is measured Meters (m)

It takes 2 seconds for two cycles to pass through a point. What is the period of this wave? 1 second

How many degrees out of phase are the following waves? 180

How many nodes and antinodes does the following standing wave have? N = 5 A = 4

An example of Resonance Wine glass Etc

The Doppler Effect An apparent change in frequency in sound emitted by a moving source is known as?

This figure shows the movement of a noisy car and the sound waves it produces, at which point would an observer hear the highest frequency? A

Name the two kinds of waves Transverse and longitudinal

Describe how the wave phenomena shown occurs Sonic Booms occur when a jet flies faster than the speed of sound

8.0/1.2 = 6.7 times the speed of sound Calculate the speed of the object if the radius of the circle is 1.2 cm and the yellow line is 8.0 cm

Destructive interference Name the phenomena shown and predict what the sum of the waves will look like

f = 3 Hz T = 1/3 s v = λf = (2)(3) = 6 m/s If a wave vibrates 3 times each second, and its wavelength is 2 meters, what is its frequency? Its period? Its speed?
