A source is approaching towards an observer with constant speed along the line joining them. After crossing the observer, source recedes from observer with same speed. Let f is apparent frequency heard by observer. Then,

A boy moving with a velocity of 20 km h^(–1) along a straight line joining two stationary objects. According to him both objects

If a particle is seen through layers of parallel glass slabs of different refractive index as shown in figure. Where mu_(0) is the medium of the observer. If the object has velocity v towarsd observer at this instant along the line joining object and observer then, which of the following correctly represent the velocity of the object as seen by observer?

Stationary Source And Moving Observer

A double-slit apparatus is used to observe an interference patten projected on a screen from a stationary light source. If the light source is instead moved toward the double slits at constant speed along the axis of symmetry. What will be observed on the screen ?
