Energy of Waves vocabulary
Term | Definition |
---|---|
wave | 1. A disturbance that transfer energy from place to place. 2. The movement of energy through a body of water. |
medium | The material through which a wave travels. |
transverse wave | A wave that moves at right angles to the direction in which the wave travels. |
longitudinal wave | A wave that moves the medium in a direction parallel to the direction in which the wave travels. |
amplitude | 1. The height of a transverse wave from the center to a crest or trough. 2. The maximum distance the particles of a medium move away from their rest positions as a longitudinal wave passes through the medium. |
wavelength | The distance between two corresponding parts of a wave, such as the distance between two crests. |
frequency | The number of complete waves that pass a given point in a certain amount of time. |
wave speed | How far the wave travels in a given amount of time. You can determine a wave's speed by dividing the distance it travels by the time it takes to travel that distance. Speed=Wavelength x Frequency; Frequency=Speed/Wavelength; Wavelength=Speed/Frequency |
reflection | The bouncing back of an object or a wave when it hits a surface through which it cannot pass. |
refraction | The bending of waves as they enter a new medium at an angle, caused by a change in speed. |
diffraction | The bending or spreading of waves as they move around a barrier or pass through an opening. |
interference | The interaction between waves that meet. |
standing wave | A wave that appears to stand in one place, even though it is two waves interfering as they pass through each other. |
resonate | To produce or be filled with a deep, full, reverberating sound. |
