1Which way is a higher pitch according to the doppler effect? Toward you Away from youTowards you
The waves are congested and sound higher
fd= (vw/vw-vs)fs
2Frequency Will the frequency remain the same once the wave is created?Yes
No matter what medium it travels in, the wave will stay in the same frequency. Frequency is said to be source dependent.
3Is speed medium dependent?Yes
Speed will change between mediums depending on the elasticity.
4What does it mean when a wave is in 'phase'?Phase is when two waves or signals have a crest or trough occurring at the same time.
5What is SuperPosition?
6What is constructive interference? Destructive?Constructive is when the amplitudes are added together to create a bigger wave while destructive is when they are added together to create a smaller wave.
- plus +
7Difference between Mechanical waves and Electro magnetic waves.Electro magnetic don't need a medium to travel while mechanical do.
8Pulse?A single disturbance of the medium
