Waves Review
Mastery Assessment Waves review
| Term | Definition |
|---|---|
| Crest | The highest point of a transverse wave. |
| Trough | The lowest point of a transverse wave. |
| Mechanical waves | Require a medium to pass through. |
| Medium | Solid, liquid, or gas |
| Longitudinal waves | move side to side and parallel to the mediums. look like a slinky |
| Transverse Waves | Waves that move perpendicular to their mediums. |
| Compressions | When a longitudinal wave is scrunched together. |
| Rarefaction | When a longitudinal wave is spread a part. |
| Frequency | How many times a wave occurs, also measures in hertz |
| Amplitude | Measured from the crest to the resting point or the trough to the resting point. |
| Speed Equals | Wavelength X frequency |
| Reflection | When a wave hits an object and bounces back. |
| Refraction | When a wave goes into a new medium and bends at an angle. |
| diffraction | a wave moving around a barrier. When it going through a tiny space and spreads out into an opening. |
| Interference | When waves meet and interact |
| Constructive interference | When waves meet and the amplitude Builds |
| Primary colors of light | Blue, green, and red- combined together they make white |
| Primary colors of pigments | Yellow, magenta, cyan- Combined together they make black. |
| Elasticity | The ability for a material to bounce back after being disturbed. |
| Pitch | How high or low the sound seems to someone. As frequency increases, this increases. |
| Doppler Effect | As an object approaches a person the pitch and frequency are higher. As the noise goes further away the pitch and frequency decrease, causing the sound to be lower. |
| Electromagnetic Spectrum | Made of waves the are electric and magnetic. We use this for communication |
