(a) In the figure shown a slab of refractive index (3)/(2) is moved toward a stationary observer with speed 6 cm//s . A point O is observed by the observer with the help of paraxial rays through the slab. Both O and observer lie in are. Find the velocity (in cm//s ) with which the image will appear to move to observer. (b) in the previous question if the object moves towards rigth with a velocity of 6 cm//s and find the velocity of the final image (in cm//s ) as seen by observer :

An observer is travelling in east with a velocity of 2 m/s and observes that wind is blowing in north with a velocity of 2m/s. If observer doubles his velocity then find out the velocity of wind appears to observer ?

Assertion : The sound emitted by the source travels in all directions. Reason : The relative velocity of sound with respect to the observer is the sum of velocity of sound and velocity of observer.

When the light source is moving towards an observer,

If an observer moves towards a stationary source of sound with a velocity of one tenth the velocity of sound, then the apparent increase in frequency will be

If a source emitting waves of frequency f moves towards an observer with a velocity (v)/(4) and the observer moves away from the source with a velocity (v)/(6) , the apparent frequency as heard by the observer will be (v=velocity of sound)

An observer moving towards a stationary source observes that the apparent frequency is three times the actual frequency of the source. If the velocity of sound is V, the velocity of the observer would be-

An observer A is at rest in gournd frame, observer B is moving with constant another observer C is moving with constant velocity of 1m/s.
