scientific wave definitions
Question | Answer |
---|---|
A disturbance that tranfers energy place to place | wave |
Mechanical waves are created when a source of energy causes a medium to | move |
The speed of a wave is its wavelength multiplied by its | frequency |
The bending of waves due to change in speed is called | refraction |
The beinding of waves around the edge of a barrier is known as | defraction |
The interaction between two waves that meet is called | Interference |
Waves combine to make a wave with larger amplitude in a process is called | constructive interference |
When an incoming wave combines with a reflected wave in such a way that the combined wave appears to be standing still, is a result of | Standing wave |
What occurs when vibrations traveling through an object match the object's natural frequency? | vibration |
a wave travels through a medium because | Energy passes from partical to partical |
Mechanical waves are classified according to | how they move |
Frequency is measured in units called | hertz |
When a wave hits a surface through which it CANNOT pass and bounces back, it undergoes | Reflection |
Waves combine to produce smaller or zero-amplitude wave in a process called | destructive interference |
Why do you see lightning from a distant storm before you hear thunder? | Because light is faster than sound |
Compressions and rarefractions are characteristics of what type of wave? | Longitudinal |
The distance between two consecutive crests of a wave is called the | Wavelength |
Amplitude | The greatest movement from its resting position, also known as the height. |
Wavelength | The distance from crest-to-crest or trough-to-trough |
Frequency | the number of complete wave cycles that pass a certain point per unit time |
Transverse waves | A wave in which the motion of the medium is at a right angle to the motion of the wave |
Elasticity | A wave travels faster through a more elastic medium |
Density | A wave travels slower through a denser medium |
Vibrations | Is a traveling disturbance that carries energy from one place to another |
crest | High point of wave |
Trough | Low point of wave |
Resting point | Starting position of wave |
