QuestionAnswer
A disturbance that transfers energy from one place to another is 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 due to a change in speed is called Refraction
The bending of waves around the edge of a barrier is known as Diffraction
The interaction between two waves that meet is called Interference
Waves combine to make a wave with larger amplitude in a process 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, the result is a Standing wave
What occurs when vibrations traveling through an object match the objects natural frequency Resonant Frequency
A wave travels through a medium because Particle to Particle
Mechanical waves are classified according to How they move
Frequency is measured in units called Hertz (Hz)
When a wave hits a surface through which it cannot pass and bounces back and undergoes bananas Reflection
Waves combine to produce a smaller or zero amplitude wave in a process called Destructive Interference
Why do you see lightning from a distant storm before you hear thunder? Light travels faster than sound
