Wave Stuff Flashcards
What are the two types of waves
Transverse and longitudinal
Nodes
With a wave meets the line
Crest
The top of a wave
Trough
The bottom of a wave
Amplitude
The length of a wave upwards
Wave length
The length of the wave
Baseline
The Center line
f = ?
Wave per sec
T= ?
Sec per wave
Approaching source
Divided on the bottom and is negative
Receding source
The bottom of the divided and positive
Observer approaching source
The top of the divided and is positive
Observer receiving from a source
On the top of the divided end is negative
What is the doppler effect
The apparent change in frequency caused by the movement of the surface of the sound
Law of reflection
The angle Of incident is equal to the angle of reflection
Unless the mirror is distorted
Convex mirror
Produces virtual images And are up right,
Makes images look far away
Concave mirror
Makes real and upside down images
Make images close up
How to make a Ray diagram
Parallel s s parallel
How to make a ray diagram when the object is on the Focal point
There is no image the lines are parallel
How to make a ray diagram when the image is in front of the focal point.
Still do parallel f but for f parallel use the center point
Convex rate diagram
For lenses use opposite f’s
