DOPPLER EFFECT PHYSICS

CLASSICAL PHYSICS

CLASSICAL PHYSICS

A : Doppler's effect in sound is asymmetric but in light , it is symmetric R : In Sound , change in frequency depends on the individual velocity of both the source as well as the observer . In light , change in frequency depends on the relative velocity between source and observer .

What is Physics?

A : In Doppler's effect the value of apparent frequency depends on the relative motion between source and observer . R : The change in frequency in Doppler effect is independent from the distance between source and observer .

Effect of Temperature on Physical State

Assertion : The increase in wavelength due to doppler effect is termed as red shift. Reason : In red shift, a wavelength in the middle of the visible region of the spectrum moves towards the violet end of the spectrum.

(A) : In Ampere Maxwell law, displacement current has same physical effect as conduction current. (R) : The units and dimensions of displacement current and conduction current are same.

Statement(A): The reflection of sound from an extended object is echo Statement(B): The super position of waves of same frequency is beats Statement(C): The apparent change in frequency of source of sound due to relative motion between source and observer is Doppler effect Statement(D): The super position of wave of slightly differ in frequency is stationary waves
