Waves |
A disturbance that transfers energy from one point to another |
|
|
What do waves travel through |
Some medium |
|
|
Two types of mechanical waves |
Transverse and longitudinal |
|
|
Transverse wave |
A typical image of a wave; particles move perpendicular to the direction the wave travels and |
|
|
Longitudinal wave |
Compression wave; compacted wave |
|
|
Medium definition |
Material that waves travel in. for example air, water, rope |
|
|
Crest and trough |
Crest is High Point of wave and trough is low point of wave |
|
|
Amplitude |
maximum displacement from rest |
|
|
Waves with higher amplitude have _____ energy |
More |
|
|
Waves with shorter wavelengths have _____ energy |
More |
|
|
Antinode |
Points were any two with friends interfere constructively.
No cross like X shape |
|
|
Nodes |
Points were two wavefronts interfere destructively.
Like X crossing |
|
|

What is the Doppler effect |
The pitch of the sound depends on the frequency of the soundwave that reach the observer |
|
|

|
|
Beat |
An interference pattern between two sounds of slightly different frequency. |
|
|
Reflected pulse on a fixed end will be: |
Inverted |
|
|
Reflected pulse on a fixed end will be: |
Inverted |
|
|
Reflected pulse with free end will be: |
Same but flipped |
|
|
Higher amplitude waves --> more ______ = ________ volume |
Energy/ volume |
|
|
Sonic boom |
When object (ex. Plane) travels faster than the speed of sound.
1) Waves fronts stacked up 2) high pressure zone created 3) anyone of ground as line of sound waves hits experiences this SONIC BOOM
- stacked up sound waves that hit you all at once; sounding like an explosion |
|
|
DIFFRACTION:
Wide gap= weak/strong diffraction effect
Narrow gap= ??
Large wavelength= ?? |
Weak
Strong
Strong |
