Physics Wave/Sound Review Flashcards
Amplitude
Height from the midline
Order of the electromagnetic spectrum
Radio, Microwave, Infrared, Visible Light, Ultra violet, x-ray, Gamma rays
Radio and television have what energy, frequency, and wavelength
Low energy, ow frequency, and long wavelength
Gamma rays have what energy, frequency, and wavelength
High energy, high frequency, short wavelength
How does a Decibel Scale work
Logarithmic, every 20 dB increase, you multiple 10
Medium
Air, water, metals
Pitch
How high or low a note is
Periodic wave
number of waves produced per unit of time
Frequency
repetitive series of pulses
Vibrate
to move back and forth rapidly
Transverse wave
The disturbance is PERPENDICULAR to the direction of the waves travel.
Longitudinal wave
the disturbance is PARALLEL to the direction of the waves travel
Surface wave
When medium’s particle follow a circular path; either both perpendicular and parallel at times.
A wave carries what through space
energy
WHat are the names of the three bones that are evolutionary important to human eharing
Stapes, Incus, Malleus
Mathematical difference between frequency and period
They are inverses of each other
Frequency
How many cycles of an oscillation occur per second
Period
Amount of time it takes a wave to vibrate one full cycle
What is the speed of sound in air at 20 degrees Celsius
343m/s
How do you determine the speed at any other degree Celsius
You add 0.6 for every increase in 1 degree celsius
