Wave
| Question | Answer |
|---|---|
| Compressional Wave | Mechanical wave that causes particles in matter to move back and forth along the direction the wave travels. |
| Diffraction | Bending of waves around an object. |
| Electromagnetic Spectrum | Complete rage of electromagnetic wave frequencies and wavelengths. |
| Electromagnetic Waves | Waves that can travel through matter or empty space, includes radio waves, infrared waves,visible light waves, ultraviolet waves, X rays, and gamma rays. |
| Frequency | Number of wavelengths that pass a given point in one second, measured in hertz. |
| Infrared Waves | Electromagnetic waves with wavelengths between about one thousandth of a meter and 700 billionths of a meter. |
| Intensity | Amount of energy a wave carries past a certain area each second. |
| Law of reflection | States that the angle the incoming wave makes with the normal of the reflecting surface equals the angle the reflected wave makes with the surface. |
| Pitch | Human perception of the frequency of sound. |
| Refraction | Change in direction of a wave when it changes speed as it travels from one material into another. |
| Reverberation | Repeated echoes of sound waves. |
| Transverse Wave | Mechanical wave that causes particles in matter to move at right angles to the direction the wave travels. |
| Ultraviolet Wave | Electromagnetic wave with wavelength between about 400 billionths and 10 billionths of a meter. |
| Wave | Disturbance that move through matter and space and carries energy. |
| Wavelength | Distance between one point one a wave and the nearest point moving with the same speed and direction. |
