Chapter 11 Wave Motion Flashcards
(3 cards)
1
Q
Intensity of a wave
A
Rate of flow of energy per unit area perpendicular to the direction of the wave
I = P/A
For point source, I = P/4πr^2
2
Q
Polarization
A
Processed by which a waves oscillation are made to occur in a single plane only
Unpolarised to polarised:
I/2
3
Q
Velocity of wave formula
A
v=fλ
