TEST 11 &12

the diagram illustrating two waves in phase is: it's the same
which of the following usually occurs inside a material instead of at the surface? absorption
a violin string vibrates at a fundamental frequency of 200 Hz. the frequency of the third harmonic for this string is 600 Hertz
a longitudinal wave travels in the same direction as the oscillations
how many anti-nodes does this standing wave have <><><> 3
an ocean has a frequency of 2 Hz and a speed of 20 m/sec. What is the wavelength of this wave? 10 meters
if you double the frequency of a pendulum, what happens to the period of one cycle? the period is 1/2 its original time
a mass oscillates on the end of a spring with a period of 4 seconds. what is the frequency of the oscillator? .25 Hz
natural frequency is: the frequency at which a system oscillates when it is disturbed
a transverse wave: oscillated perpendicular to the direction of wave travel
although a door is only slightly open, sound will pass from one room to another due mainly to: reflection
sound waves are always: longitudinal waves
which factor listed below has the greatest effect on the period of a pendulum? length of the string
destructive interference occurs because: multiple waves combine to make a wave of smaller amplitude
the wavelength of a wave is defined as the distance from crest to crest
when a guitar is plucked it vibrates at its fundamental. If a guitar string is 68 cm long, what is the speed of the wave on a string if the fundamental frequency of the guitar string is 262 hertz? 356 m/sec
eyeglasses bend light waves by the process of refraction
the amplitude of a pendulum is doubled. this means the pendulum will swing twice as far away from the center.
when a wave reflects from a hard surface, it may do all of the following except- change from transverse to longitudinal
if the length of a pendulum increases, the period of the pendulum increases
a vibrating string has a natural frequency of 30 hertz the string will also be resonant at 60 Hertz
a piano is the approximate wave length in centimeters of this sound wave if the speed of sound in air is 340meters per second? 77 centimeters
time for one cycle to occur period
a single unit of periodic motion cycle
distance from one point on a wave to the same point on the next wave wavelength
unit of measurement for frequency (one cycle per second) Hertz
happens when two or more waves interact interference
multiples of the fundamental harmonics
a group chosen to include all those thing of interest to be studied decibel
a system that shows harmonic motion oscillator
the maximum response to an oscillating force occurring at a natural frequency resonance
number of cycles that occur in one second frequency
