It’s the frequency of a sound wave. A sound wave has this form.
1 PT Pitch
Mechanical waves such as sound waves travel fastest through this
2 PT Solids (the particles are closest together).
A sound wave is this type and form of wave.
3 PT Mechanical and longitudinal (or compressional)
It’s another name for the energy of a wave; related to the amplitude
4 PT Intensity
It’s the spread-apart portion of a sound wave
5 PT rarefaction
Loudness is measured in these units
1 PT Decibels (dB)
This wave phenomenon is caused by a shift in frequency due to the motion of the source of a wave relative to the observer.
2 PT The Doppler Effect
It’s the direction a galaxy is moving when the galaxy is perceived to be red shifted.
3 PT Away from the observer
Ships use this technology with sound waves to locate submarines under water.
4 PT SONAR
The character of this determines the speed of any wave.
5 PT The medium through which the wave travels
The unit for frequency (and pitch)
1 PT Hertz (Hz)
It’s the type of wave shown below
2 PT transverse
It’s the speed of a sound wave that has a frequency of 33.3 Hz and a wavelength of 10 m.
3 PT 333 m/s
It’s the type of relationship that exists between frequency and wavelength
4 PT Inverse relationship
The number of nodes, antinodes and wavelengths shown below
5 PT 4 nodes, 3 antinodes and 1 ½ wavelengths
Sound waves and seismic waves represent this broad class of waves.
1 PT Mechanical waves
The tiny hairs in this part of the ear resonate to different frequency
2 PT The Cochlea
Changes in the tension or length of the vibrating medium causes this wave charcteristic to change
3 PT Pitch
It’s the beat frequency produced by 441 Hz and 448 Hz tuning forks
4 PT 7 beats per second
A radio wave is an example of this broad wave category
5 PT Non-mechanical wave
It’s the normal audible range of hearing for humans
1 PT 20 – 20,000 Hz
It’s the two terms used to describe frequencies above and below our normal range of hearing
2 PT Infrasound (below) and Ultrasound (above)
These types of waves travel slowest through solids and fastest through a vacuum
3 PT Non-mechanical waves (light waves or electromagnetic waves)
This wave phenomenon develops when the vibrations of one object match the natural frequency of another object, causing it to increase in amplitude.
4 PT resonance
This wave phenomenon occurs when two identical waves constructively and destructively interfere to form nodes and antinodes.
5 PT Standing waves
Mechanical Waves and Sound
Waves & Sound A. Waves 1. The nature of waves
A disturbance in a medium that transfers energy and momentum
CP Physics Ms. Morrison. Mechanical – needs medium Longitudinal Created by vibrations which disturb the medium and transmit the wave energy Sound.
Sound Chapter 26.
Principles of Physics. Sound Result of vibration of air particles around a source Longitudinal wave – air particles get compressed and spread apart as.
Properties of sound Sound is a longitudinal wave Longitudinal waves travel at different speeds depending on the medium 25 o C 346m/s, water 1490.
SPH3U Exam Review Waves and Sound.
All sounds are produced by the vibration of matter. If there is no vibration, there is no sound.
By Aimee Chavez. Wave: a disturbance that transfers energy from place to place. The material through which a wave travels through is called a medium.
Bell Work: Test Review 1. What is the range of human hearing?
Mechanical Waves and Sound Ch. 17 Physical Science.
Waves & Sound.
WAVE CHARACTERISTICS. TRANSVERSE WAVE Crest: highest point of a transverse wave. Trough: lowest point of a transverse wave. Amplitude maximum distance.
Vibrations, Waves, & Sound
Chapter 17: Mechanical Waves and Sound
Waves / Sound Physics. Waves Wave motion is the means of transferring energy through a medium without the material itself moving along with the energy.
