Vocabulary
The matter through which a wave travels
What is a medium
A disturbance that carries energy through matter or space.
What is a wave
Are measurements of distance
What is Amplitude and wavelength
When a wave meets a surface or a boundary, the wave bounces back.
What is reflection?
Results from interference between a wave and its reflective wave.
What is a standing wave
Waves in which the motion of the particles is perpendicular to the motion of the wave
What are transverse waves
The ability to exert a force over a certain distance, or to do work.
What is Energy
The time required for one full wavelength of a wave to pass a certain point
What is a period
Simply the bouncing back of a wave when it meets a surface or boundary.
What is reflection
The bending of waves when they pass from one medium to another
What is refraction?
Changing electronic and magnetic fields in space.
What are Electromagnetic waves
An example of longitudinal waves that we encounter everyday.
What are Sound waves
The source of waves and the observer creates a change in observed frequency.
What is motion
When several waves are in the same location, they combine to produce a single, new wave that is different from the original waves.
What is interference
The speed of a wave is equal to wavelength divided by period, or to frequency multiplied by wavelength.
What is wave speed
The greatest distance that particles are displaced from their normal resting positions.
What is amplitude
The boundary between two different mediums, such as water and air.
What are Surface waves
This effect can result from the motion of the source or the observer or both.
What is the Doppler effect
The particle moves up 4 cm because of one wave and 3 cm because of the other, for a total displacement of 7 cm.
What is constructive interference
What does Mrs. Hills teach?
What is Physical Science
The distance from one crest to the next crest, or from one trough to the next trough
What is wavelength
A wave in which the wave motion is perpendicular to the particle motion.
What is a transverse wave
Can travel through the air. If they couldn’t, you would not be able to have a conversation with a friend or hear music across the room.
What are Sound waves
Something that causes the medium to vibrate in a stationary pattern that resembles a loop or series of loops.
What are Standing waves
Midway between the nodes lie points of maximum vibration.
What are antinodes.
