- vibration
- back and forth motion of an object.
- wave
- disturbance that propagates through a medium or space.
- what do we need to send information?
- medium
- back and forth motion of an object is called?
- vibration.
- disturbance that propagates through a medium or space is called a...
- wave
- we send information through these two types of waves.
- wave motions and particle motions
- 1 complete vibration is...
- point A to B back to A.
- moving from point A to B to point A is...
- 1 complete vibration.
- what two things effect the motion of the pendulum?
- acceleration due to gravity and length of the pendulum.
- T/F: Mass affects the motion of the pendulum.
- False. Mass does NOT affect the motion of the pendulum.
- what is the formula for finding the period of a pendulum?
- T= Time of Vibration(s)/ # of Vibrations(vib/s)
- what is the period of a pendulum?
- 1 complete vibration.
- all waves have these 5 properties...
- interference, reflection, refraction, diffraction, dispersion.
- the crest is...
- the waves highest point.
- the trough is...
- the waves lowest point.
- the distance from one crest to another crest, or one trough to another trough, is called...
- wavelength
- frequency is...
- the number of vibrations per second.
- the number of vibrations per second is...
- frequency
- the formula for finding the speed of the wave is...
- V=lambda/T or wavelength divided by the period of the pendulum.
- T/F: The period of the pendulum is INVERSE to the frequency.
- True.
- a single harmonic motion (SHM) is...
- continuous external force on an object to keep the motion going.
- A continuous external force to keep the motion of the object moving is called...
- single harmonic motion (SHM).
- removal of an external force is...
- damped harmonic motion (DHM).
- If the motion of the particles are in the same direction the pressure was forced is called...
- longitudinal or compression wave.
- motion of the particles move perpendicular to the motion of the force is called...
- transverse or sheer waves.
- interference happens when...
- a wave and another wave coming in the same or opposite direction collide with each other.
- interference happening can result in a ___ or ___ interference.
- destructive or constructive.
- Constructive interference means...
- a larger wave is produced if the crest matches the crest of another wave.
- destructive interference means...
- both waves have been depleted when the crest matches the trough of another wave.
- change in frequency due to relative motion between the source and the observer is known as...
- the Doppler effect.
- radio detecting range used for light waves is known as...
- Radar
- Sound navigation detecting range used for sound waves and good when looking for depth and the location of an object is known as...
- Sonar
- what happens to the wavelength when you keep frequency the same and you increase the speed of a wave?
- the wavelength increases as well.
- how much does a wave travel in 1 period?
- 1 wavelength.
