Module 9 Test Flashcards
In a transverse wave, how does the medium vibrate?
at right angles to the wave direction
What happens to wavelengths when the frequency is lower?
they get longer
Do sound waves oscillate parallel or perpendicular to the direction in which the wave travels?
parallel
What is the formula for the speed of sound?
What is the formula for distance using sound
Why is the slogan, “In space, no one can hear you scream.” true?
there is little to no air in space and sound waves cannot travel
What happens to frequency if the wavelength is doubled?
its halved
a wave that travels along the survace of a medium
surface wave
any speed that is faster than the speed of sound in the medium of interest
supersonic speed
a disturbance in matter that transfers energy through the matter
mechanical wave
a wave in which the vibration of the medium is parallel to the direction the wave travels
longitudinal wave
What is the formula for frequency of a sound wave.
an indication of how high or low a sound is, which is primarily determined by the frequency of the sound wave
pitch
a wave in which the medium vibrates at right angles to the direction the wave travels
transverse wave
