reflection of light / Image formation in plane mirrors

OPTICS

It is the branch of Physics that STUDIES THE BEHAVIOR AND PROPERTIES OF LIGHT, including its interactions with matter and the use and construction of instruments that use or detect it.

REFLECTION

-is simply the BOUNCING BACK OF A LIGHT when it encounters an obstacle (object / surface)
-occurs when light waves are incident on a surface, and so, it will _______ light away from the surface at the same angles as they arrive

predictable manner

LIGHT behaves in a very

REGULAR / SPECULAR
IRREGULAR / DIFFUSE

TWO TYPES OF REFLECTION:

REGULAR / SPECULAR

Light is reflected from a SMOOTH SURFACE at a definite angle

IRREGULAR / DIFFUSE

Light is reflected from a ROUGH SURFACE in all directions

Materials that are VERY SMOOTH or POLISHED metals

MATERIALS THAT REFLECT LIGHT?

OPAQUE Materials

do not allow light to pass through them; they only ABSORB AND REFLECT LIGHT.

LOCATION: Behind the Mirror
ORIENTATION: Upright / Erect
SIZE: Same Size as Object
TYPE: Virtual

IMAGE FORMATION IN PLANE MIRRORS:
LOCATION:
ORIENTATION:
SIZE:
TYPE:

LATERALLY REVERSE

IMAGES produced by PLANE MIRRORS are

LESS

The GREATER is the angle between two mirrors, the _______ number of images is formed

An INFINITE NUMBER of Images will be produced

What about if we place two plane mirrors in front of each other?

PERISCOPE

An instrument that uses a system of mirrors to REFLECT IMAGES THROUGH A TUBE

KALEIDOSCOPE

Invented by Sir David Brewster in 1816, a TOYwith two or more mirrors producing virtual images of STUNNING BEAUTY
