In the context of Doppler effect in light, the term red shift signifies

Doppler effect is applicable to

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.

Dopper's effect is sound in addition of relative velocity between source and observer, also depends while source and observer or both are moving. Doppler effecct in light depennd only on the relative velocity of source and observer. The reason of this is

A light enters a glass slab of thickness t with angle of incidence i suffers lateral shifts(s).If angle of refraction of light is r , then lateral shift is equal to

Define the term 'Tyndall effect'.

A rose appears red in light of all the colours.

A : More accurate formula for the Doppler effect which is valid when the speeds close to that of light, requires the used of Einsteins special theory or relativity. R : Doppler effect is the basis for the measurements of the raidal velocities of distant galaxies.

Is there a Doppler effect in the case of sound when the observer or the source moves at right angles to the line joining them? How then can we determine the Doppler effect when the motion has a component at right angles to this line?
