MIRROR Flashcards
is not exactly a silvered plate of glass. Rather, it is any surface that is smooth enough to produce a regular reflection of light incident upon it.
Mirror
two types of mirror
o Plane mirror
o Spherical mirror
is one with a flat surface. The ordinary mirror you have at home where you see the exact image of yourself is a plane mirror.
Plane Mirror
are also used by architects or interior designers to make room appear bigger.
Plane mirrors
A _________ has a reflecting surface taken from the surface of a sphere. It may be concave or convex
spherical mirror
A ___________ curves inward in the direction of the incident rays. The hollow part of a shiny spoon is a concave mirror. But if you turn over it becomes a ___________
concave mirror
convex mirror
is the bouncing of light into the same medium it has been travelling after striking a surface
Reflection
– the ray that strikes the surface
Incident ray
– the ray that rebounds from the surface
Reflected ray
– a line perpendicular to the surface at the point of incidence
Normal
– the angle between incident ray and normal
Angle incidence
–the angle between reflected ray and normal
Angle of reflection
TWO TYPES OF REFLECTION
Specular or Regular Reflection
Diffuse Reflection
– reflection from smooth surface
Specular or Regular Reflection
–reflection from rough surface
