The velocity of light emitted by a source S observed by an observer O , who is at rest with respect to S is c . If the observer moves towards S with velocity v , the velocity of light as observed will be

An observer measures speed of light to be C, when he is stationary with respect to the source. If the observer moves with velocity V towards the source then the velocity of light observed will be

(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 ?
