REFLECTION AND MIRRORS
Reflection is a property of light that occurs when light bounces back as it hits a surface. This is the
main reason that you are able to see the objects around you. Some objects are capable of producing
their own light, such as the sun and the stars. Other artificial light sources such as lamps and bulbs give
off their own lights.
● Law of Reflection - the angle of reflection is the same as the angle of incidence
Types of Reflection
Regular Reflection
- parallel orientation
- reflected in the same direction
Diffused Reflection
- light is reflected in multiple
directions
Mirrors - reflective Plane mirrors - flat Curved mirrors - a curved reflecting
surfaces made up of surfaces that reflect light surface, can be either concave or
glass convex
Plane Mirrors
- The images produced are laterally inverted (left-to-right reversal)
- The distance of the image to the mirror is the same as the distance of the real object to
the mirror
- The size of the virtual image formed by the plane mirror is exactly the same size as the
size of the real object.
Curved Mirrors
- produce images of different sizes and locations
Convex Concave
- bent outward - “caves” inward
- Incident light rays are spread out and - Incident light rays are brought to a certain
dispersed point
