Wave Motion Flashcards
Difference between stationary and progressive wave
In stationary wave, there is no transfer of energy from one point to another point while there is a transfer of energy between points in a progressive wave.
Differentiate Phase difference between waves and particles
Phase difference between particles shows much one particle lags or leads another wrt to a cycle while phase difference between waves shows how one waves lags or leads another. Phase difference/2pie = time lag/T
Define Intensity of a wave
It is the rate at which energy is received per unit area perpendicular to the direction of propagation of the energy. intensity= power/cross-sectional area = P/4pier^2. ( I is inversely proportional to r^2 and I is directly proportional to Amplitude^2)
Define Polarisation
It is the phenomenon in which a transverse wave is restricted to propagate in only one axis of vibration perpendicular to wave propagation.
State Malus’ Law
Malus’ Law states that when a polariser is placed i the ath of a polarised beam of light
