The reason you can’t hear sound while in a vacuum Because it is a mechanical wave, it needs a medium Category 1 - 10

The speed of sound will change if you change its: Medium Medium Amplitude Loudness Category 1 - 20

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 (pitch)?

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

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

Which wave is the loudest? Up and down

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

Sound moves in what direction? Away from sound source in all directions

What creates sound waves The vibration of an object?

True of False: Sound waves are longitudinal

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

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

What is the unit for loudness? decibels

The longer the wavelength of a wave, the _____ the frequency and therefore the pitch? Smaller/lower

A reflected sound wave is called An echo

Uses of reflected sound waves include Echolocation, Ultrasounds and SONAR.
