Question | Answer |
---|---|
A disturbance that transfers energy from place to place is called a | 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 around the edge of a barrier is known as | Diffraction |
The bending of waves due to a change in speed is called | Reffraction |
The interaction between two waves that meet is called | Interfearence |
Waves combine to make a wave with larger amplitude in a process called | Constructive Interfearence |
When an incoming wave combines with a combines with a reflected wave in such a way that the combined wave appears to be standing still,the result is a | Standing Wave |
What occurs when vibrations traveling through an object match the object's natural frequency? | Resanants |
A wave travels through a medium because | Energy passes from particle to particle |
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 a smaller or zero-amplitude wave in a process called | Destructive Interfearence |
Why do you see lightning from a distant storm before you hear thunder? | Because the speed of light is faster than the speed of sound. |
