2. A large fish with a mass of 1-kg is in motion at 45 cm/s when it encounters a smaller fish
(m=0.25 kg) that is at rest. The large fish
swallows the smaller fish and continues in
motion at a reduced speed. Fill in the before-
and after-collision table below.

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
