Waves
Question | Answer |
---|---|
Wave | A disturbance the moves through matter or space. |
Transverse Wave | Causes particles in matter to move back and forth at right angles to the direction in which the wave travels. |
Compressional Wave | Causes particles in matter to move back and forth along the same direction in which the wave travels. |
Wavelength | The distance between one point of the wave to the nearest point of the wave. |
Frequency | Is the number of wavelengths that pass by a point each second. |
Law of Reflection | Specular reflection the angle at which the wave is incident on the surface equals the angle at which it is reflected. |
Refraction | The change in direction of a wave when it changes speed as it travels from one material into another. |
Diffraction | Bending of waves around an object |
Opaque | An object that allows no light to pass trough it. |
Transparent | An object allows all light to pass threw it. |
Translucent | An object that allows some light to pass trough it. |
Reflect | Bounce off. |
Absorbs | Take light in. |
Transmit | Go threw it. |
Loudness | It relates through amplitude because you need more energy to make a louder sound. |
Pitch | It relates to frequency because frequency is higher pitch. |
Echolocation | Some Animals used this method to navigate and hunt. |
Echo | A reflective sound wave. |
Doppler Effect | The change in in frequency that occurs when a source of sound is moving relative to a listener. |
