Question
Answer
Wave   A disturbance that transfers energy from place to place.  
🗑
Medium   Material through which a wave travels  
🗑
Transverse   Waves that move the medium at right angles to the direction of the wave  
🗑
Longitudinal   Waves that move the medium parallel to the direction of the wave  
🗑
Crest   The highest part of a transverse wave  
🗑
Trough   The lowest part of a transverse wave  
🗑
Compression   The part of a longitudinal wave where the particles of closer together  
🗑
Rarefaction   The part of a longitudinal wave where the particles are farther apart.  
🗑
Amplitude   The maximum distance that the particles of the medium move from their rest position  
🗑
Wavelength   The distance between two corresponding parts of a wave  
🗑
Frequency   The number of complete waves that pass by a given point in a certain amount of time  
🗑
Hertz   Unit for frequency  
🗑
Sound   A disturbance that travels through a medium as a longitudinal wave  
🗑
Loudness   Your perception of the energy of a sound. It depends upon the amplitude of a sound wave and the distance from the source.  
🗑
Pitch   A description of how high or low a sound seems to a person. It depends upon the frequency of a sound.  
🗑
Mechanical   Waves that require a medium through which to travel  
🗑
Visible Light   Electromagnetic waves that humans can see  
🗑
White Light   A mixture of all the colors of visible light  
🗑
Transparent   Material that transmits most of the light that strikes it  
🗑
Translucent   Material that scatters light as it passes through  
🗑
Opaque   Material that reflects or absorbs all of the light that strikes it  
🗑
Convex   A lens that is thicker at the center and thinner at the edges  
🗑
Concave   A lens that is thicker at the edges and thinner at the center  
🗑
Reflection   When a wave hits a surface and it bounces back  
🗑
Refraction   When a wave enters a new medium at an angle, causing the wave to bend  
🗑
