Light and Reflection

reflection of rays on a regular surface

reflection of rays at many scattered angles, on an irregular surface

real images are formed through the real intersection of lightrays. virtual images are formed through the imaginary intersection of lightrays.

on the left side

on the right side

upright, reduced, virtual

-mostly real, sometimes virtual -upright -enlarged

normal light, when reflected splits and turns into a rainbow

forms dark shadows

less dark shadow

the darkest part of a shadow

half shadow region occurs when light source is partly coved by a screen

ray of light that falls on a surface

light ray that is reflected from a surface

incidence

reflected

the ray that is found in the middle of an incident ray and a reflected ray

angle of incidence

angle of reflection

angle of incidence is equal to angle of reflection, the normal, incident and reflected rays must be on the same plane and meet on the same point

plane, convex, concave

virtual, upright, reversed

object distance equals to image distance

appears in from of the mirror (can be projected onto a screen)

appears behind the mirror

object height

image height

object distance

image distance

focal point

Center of curvature

point at which mirror and principal axis meet

image formed is reduced, real, inverted, di < do

image formed is enlarged, real, inverted, di > do

no image formed

upright, enlarged, virtual

hi/ho or -(di/do)

kaleidoscope, periscope

image distance

object distance

when the object is placed in between the focal point (F) and the mirror
