Crest | highest point of a transverse wave |
Compressional wave | A type of wave where the matter in the medium moves back and forth in the same direction that the wave travels |
Amplitude | A measure of the energy carried by a wave |
Wavelength | distance between one point on a wave and the nearest point just like it on the following wave |
What do waves transfer through matter and space? | Energy |
Rarefaction | The least dense region of a compressional wave |
Refraction | bending of a wave as it changes speed, moving from medium to another |
Medium | Any material that a wave transfers energy through |
Wave | A rhythmic disturbance that transfers energy through matter or space; exists only as long as it has energy |
Trough | lowest point of a transverse wave |
Frequency | Measures how many wavelengths pass a fixed point each second and is expressed in Hertz (Hz) |
Transverse wave | A type of wave where the matter in the medium moves back and forth at right angles to the direction the wave travels |
Resonance | ability of an object to vibrate by absorbing energy at its natural frequency |
Standing wave | A type of wave that forms when waves of equal wavelength and amplitude continuously interfere with each other |
_____ is the lowest point in transverse waves | Trough |
A medium can be either _____,______,or,___ | Solid,liquid,gas |
Diffraction | Describes the bending of waves around a barrier |
The more energy a wave carries, the ______ its amplitude | Larger |
Interference | Occurs when two or more waves overlap and combine to form a new wave |
Constructive | when two or more waves overlap and combine to form larger wave |
Destructive | when two or more waves overlap and combine to form a smaller wave |
_________ waves have crests, and troughs | Transverse |
