Question | Answer |
Frequency | The number of crests/troughs that pass by a given point per second. |
Wavelength | The distance between two crests/troughs in a wave. |
Transverse wave | A wave where the medium moves perpendicular to the direction of the wave. |
Longitudinal Wave | A wave where the medium moves parallel to the direction of the wave. |
Medium | Material in which a wave travels. |
Mechanical Wave | A wave that is caused when energy causes a vibration thru a medium. |
Electromagnetic Wave | A wave that does not travel through a medium and can travel through empty space. |
Compression | The area in a longitudinal wave where the particles are close together. |
Crest | The highest point of a transverse wave. |
Energy | The ability to move or change an object, or what a wave carries. |
Rarefaction | Area in a longitudinal wave in which the particles are spread out. |
Trough | The lowest point of a transverse wave. |
How does a particle in a surface wave move? | Circular |
What is frequency measured in? | Hz (Hertz) |
Period | The time between crests/troughs. |
What is the formula to calculate wave speed? | Frequency * wavelength |
What do ALL waves carry? | Energy |
Reflection | Bouncing of wave as it hits a surface. |
Refraction | Bending of waves as it moves through different substances. |
Diffraction | The bending of waves around a barrier. |
What are the two types of interference? | Constructive & Destructive. |
