Vibrations/pendulum
How does a vibration work?
Vibration is the repeated back-and-forth motion of a particle when displaced from its equilibrium position.
What is a wave?
A wave can be described as a disturbance that travels through a medium from one location to another location
What is a sound wave?
vibrations that travel through the air or another medium as an audible mechanical wave.
What's the formula for speed?
Speed = Wavelength x Frequency
When high pitches are produced, what kind of pitch is it described as?
high-frequency sounds are described as having a high pitch
What are the two mechanical waves?
Longitudinal and transverse wave
What's the unit of frequency?
Hertz
What's the formula for a pendulum?
T = 2π Square root of√L/g
What type of wave is produced in a guitar string?
What is a medium?
What do sound waves do when they are produced in a slinky toy?
The air molecules move back and forth in the same direction
What's the formula for Period?
P = Time taken (T) : Cycle of wave (c)
Two pendulum's with different lengths will have different periods, which pendulum will have a longer period?
The longer string will have the longer period
What are Simple harmonic motions?
Simple harmonic motion is the motion in which the object moves to and fro along a line
Why are sound waves called longitudinal waves?
The movement of the particles’ vibration is parallel to the direction of the wave propagation. In conclusion, they are called longitudinal waves.
What type of waves are ripples in water?
The waves move in a transverse motion
Just as pendulums act like clocks, would the mass affect the pendulum frequency?
If waves were at still as time, what type of wave would it be?
A standing wave
If the frequency of a wave increases, what would change about the period?
It would decrease
What type of waves are in a earthquake?
Sesimic waves
