What is oscillation?
A 100
An `Etude is a short complex musical composition.
Another ‘tude that refers to the amount of displacement
from equilibrium for any vibrating body.
A 200
What is amplitude?
A 200
What is restoring?
A 300
What is the displacement from equilibrium?
A 500
Among many other pendulum experiments, he timed the swaying movement of a
chandelier in a Pisa cathedral with his pulse.
B 200
What is the length?
B 300
At this pendulum position during its swing, restoring force and acceleration are said to be at
maximum and speed is zero.
B 500
What is at maximum displacement?
(At equilibrium, the restoring force and acceleration are
zero, and the speed is at the maximum.)
B 500
What is from one point on the wave, such as on the crest, to another
analogous or related point on the wave, such as on the next crest?
C 200
This describes the direction of a medium’s particle displacement, in relation to a transverse wave’s
direction of travel in that medium.
C 300
All waves transfer this from one location to another.
C 400
What is energy?
C 400
This wave pattern, such as in a taut string, appears to be stationary as it is it moves
between fixed points.
C 500
What is a standing wave pattern?
C 500
What is longitudinal or compression?
D 100
This name is given to the changes in pitch, perceived
by someone standing still, as a siren-blasting fire engine
moves towards, and then past, that person.
D 300
What is the Doppler Effect?
D 300
What is the sine (sinusoidal) wave?
D 400
What is at supersonic speeds a pressure field is confined to a region extending mostly to the rear and extending from the jet in a restricted
widening cone (called a Mach cone).
The sound waves combine behind the jet to form a “wake” which causes the loud boom.
D 500
The point in a standing wave that remain stationary, and the areas that are vibrating.
(You must give both terms.)
E 300
When two wave pulses pass on opposite sides of the
equilibrium position, and they completely cancel each other
out, this has happened.
E 500
F 400
This is happens when an object, vibrating at the same natural frequency of another object, causes the second object to
vibrate.
The ____________ harmonic frequency has the greatest
possible wavelength and therefore also had the lowest possible
frequency. (This is the word that correctly
fills the blank.)
