When the light source is moving towards an observer,

wavelength of light decreases.

wavelength of light increases.

wavelength of light remains unchanged

velocity of light increases

the source and the observer are moving in the same direction

the source and the observe are both at rest

there is a relative motion between the source and the observer

there is a resultant motion between the source and observer.

Both source and listener are at rest and the medium is moving

Source and listener move in same direction with same speed.

When source is at centre of a circle and listener is moving along that circle with uniform speed.

When listener is at centre of a circle and source is moving along the circle with uniform speed.
