1.	What is Doppler's effect in light ? Define red shift and blue shift in it.
Answer» When their is a relative motion between source and observer then their is change in wavelength as well frequency which is called the Doppler's effect Red shift : When their is a receding case (moving away from each other) between two then wavelength will increases that called red shift. Blue shift : when their is approaching case (moving towards each other) between two then wavelength will decrease called blue shift.
