wave
Question | Answer |
---|---|
A travelling disturbance that carries energy from one place to another | 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 a wave do to 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 | standing wave |
What occurs when vibrations traveling through an object match the objects natural frequency | Resonance |
A wave travels through a medium becuase | energy passes from 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 which it cannot pass and bounces back, it undergoes | reflection |
