11 Wave Motion Flashcards
1
Q
define intensity
A
The intensity of a wave is the rate of flow of energy per unit area perpendicular to the direction of the wave
2
Q
define polarisation
A
Polarisation is a process by which a wave’s oscillations are made to occur in a single plane only
3
Q
intensity is proportional to
A
I ∝ A^2
4
Q
Formula for amplitude of polarised wave
A
A=Aoriginal cos(angle of polarisation)
5
Q
wave definition
A
A wave is a propagation of a disturbance which transfers energy from one point to another without the physical transfer of the medium. The source of any wave is a vibration or an oscillation.
