When light bounces off a surface the same way the light hits the surface it is called reflection, refraction however is different but similar. Refraction happens when light hits a surface but unlike reflection the light changes direction. Reflection & refraction can occur in a variety of surfaces, Convex & Concave mirrors & lenses are a couple of examples. Convex mirrors & lenses are curved outwards, this causes the light to change direction when it hits the mirror.
Convex mirrors & lenses redirect light outwards from the centre. The focal point of Convex mirrors & lenses is behind the mirror or lenses. An example of a Convex mirrors or lenses that we can see in daily life are magnifying glass, side view mirrors in cars, the back side of a spoon, etc.
Concave mirrors & lenses are similar to Convex but the light is redirected inwards. The focal point of Concave mirrors & lenses are in front of the mirror & lenses. We could actually view in the focal point of a Concave mirror unlike Convex mirrors where the focal point is inside or behind the mirror which we cant see any images. Examples of Concave mirrors & lenses in daily life is flashlights, the inside of a spoon, concentrating solar collectors, etc.
