Wave Review

7th grade science

A disturbance that transfers energy from one place to a place is called a wave
Mechanical waves are created when a source of energy causes a medium to move
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 residence
A wave travels through a medium because energy is passed from particle to particle
Mechanical waves are classified according to how they move
Why do you see lightning from a distant storm before you hear thunder light is faster than sound
Compressions and rarefactions are characteristic of what type of wave? longitudinal
The interaction between two waves that meet is called interference
Waves combine to make a wave with larger amplitude in a process called constructive
The bending of waves around the edge of a barrier is known as differaction
The bending of waves due to a change in speed is called refraction
Frequency is measured in hz (Hertz)
Wavelength is measured in m (meters)
Frequency equals: speed/wavelength
Wavelength equals: speed/frequency
Speed equals: wavelength times frequency
The speed of a wave is its wavelength multiplied by its frequency
When a wave hits a surface through which it cannot pass and bounces back , it undergoes reflection
The distance between two consecutive crests of a wave is called the wavelength
