Pendulum Waves Sound More Waves AssortedVocabulary
This word means vibration.
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
This word describes any force that acts to bring a body back
to equilibrium
A 300
The unit of vibrational frequency has this name, and
these units.
A 400
What is Hertz, and cycles per second?
A 400
During a vibration, this is directly proportional to the restoring force.
A 500
What is the displacement from equilibrium?
A 500
The mass at the end of the pendulum string goes by this
familiar man’s name.
B 100
What is bob?
B 100
Among many other pendulum experiments, he timed the swaying movement of a
chandelier in a Pisa cathedral with his pulse.
B 200
Who was Galileo?
B 200
Generally speaking, this is the only factor
that influences the period of a pendulum.
B 300
What is the length?
B 300
If on another planet, this aspect related to that planet
can affect the pendulum period.
B 400
What is free-fall acceleration “g” on that planet?
B 400
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
This is high point in a transverse wave form
(above the equilibrium).
C 100
What is the crest of the wave?
C 100
This is how the wavelength measured?
C 200
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
What is perpendicular to the wave’s direction of travel?
C 300
DAILY DOUBLE
C 400
DAILY DOUBLE
Place A Wager
All waves transfer this from one location to another.
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
This is the type of wave form that carries sound
energy.
D 100
What is longitudinal or compression?
D 100
This is an area of the longitudinal wave in which the particles in the medium
spread out.
D 200
What is rarefaction?
D 200
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
The parts of this trigonometric wave are often compared to the portions of
the sound wave.
D 400
What is the sine (sinusoidal) wave?
D 400
This is way a sonic boom is created as a jet
breaks the sound barrier.
D 500
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
This is the lower part of the transverse wave form.
(below the equilibrium)
E 100
What is a trough?
E 100
As the wavelength increases this happens to the
frequency.
E 200
What is the frequency decreases?
E 200
The point in a standing wave that remain stationary, and the areas that are vibrating.
(You must give both terms.)
E 300
What are nodes (stationary points) and antinodes (areas
of vibration)?
E 300
This happens to wave pulse amplitudes during
constructive interference?
E 400
What is they add together?
E 400
When two wave pulses pass on opposite sides of the
equilibrium position, and they completely cancel each other
out, this has happened.
E 500
What is complete destructive
interference?
E 500
This is the reflection of sound arriving sometime after the
original directed sound.
F 100
What is an echo?
F 100
This is the bending of waves as they travel from one medium to another.
F 200
What is refraction?
F 200
This is bending of waves around obstacles or through openings.
F 300
What is diffraction?
F 300
F 400
This is happens when an object, vibrating at the same natural frequency of another object, causes the second object to
vibrate.
What is resonance?
F 400
The process of causing a disturbance which produces a wave.
F 500
What is propagation?
F 500
