| Question | Answer |
|---|---|
| moves the medium at right angels to the direction in which the wave travels | Transverse waves |
| moves the medium parrel to the idrection of wave | longitudinal wave |
| where the coils are close together | compression |
| where the coils are speard out | rarefaction |
| distance between 2 corresponding parts of a wave | wavelength |
| frequency is measured in units called | hertz |
| is the maximum distance that the particles of the medium carrying the wave move away from their rest position | amplitude |
| is a disturbance that transfer energy from place to place | waves |
| waves require a medium through which to travel | mechanical waves |
| the material through which a wave travel | medium |
| is the number of complete waves that pass a given point in a certain amount of time | fequency |
| the high point of a wave | crest |
| the low point of a wave | trough |
| interaction with a surface | reflection |
| angle of incidence is equavilent to angle of reflection | law of reflection |
| bending of waves due to change of speed | refraction |
| monuevers around a object or through all opening in a barrier, it bends and spreads out | diffraction |
| Interaction between waves that touch | interference |
| one wave has a larger amplitude is the sum of original crest | constructive interference |
| each amplitude meet in triugfh nd cancel out | destructive interference |
| apperars staying one place, even if two waves interfer as they pass | standing wave |
| zero amplitude | nodes |
| maxium amplitude | antinode |
| increase in amplitude of a vibration that match | resonance |
| sound waves that are reflected that you hear | echo |
| the ability for a material to bounce back aftering being disturbed | elasticity |
| echo | reflected sound |
| sound waves that spread out | defractedsound |
| when sound waves interact with each other in a construtive or distrutive sound | interference |
| The perception of the energy of a sound loudness | loudness |
| cochleIn the ear, a fluid-filled cavity that is shaped like a snail shell is the | cochle |
| A system of using reflected sound waves to detect and locate object underwater | sonar |
| is the mass per unit | density |
| is a set of notes that are pleasing | music |
| is a small, drumlike membrane | eardrum |
| is a picture made using reflected ultrasound waves | sonogram |
| The lowest natural frequency of asound is | fundamental tone |
