Objects like the sun that give out or emit light of their own are called  apertureartificialblackclear imagesenergyluminous bodiesluminous objectsmirrorOpaqueopaque objectoppositePinhole camerareflectionShadowsstraight linetranslucenttransparent.

If we cannot see through an object at all, it is an  apertureartificialblackclear imagesenergyluminous bodiesluminous objectsmirrorOpaqueopaque objectoppositePinhole camerareflectionShadowsstraight linetranslucenttransparent.

If you are able to see clearly through an object, it is allowing light to pass through it and is  apertureartificialblackclear imagesenergyluminous bodiesluminous objectsmirrorOpaqueopaque objectoppositePinhole camerareflectionShadowsstraight linetranslucenttransparent.

There are some objects through which we can see, but not very clearly. Such objects are known as
 apertureartificialblackclear imagesenergyluminous bodiesluminous objectsmirrorOpaqueopaque objectoppositePinhole camerareflectionShadowsstraight linetranslucenttransparent.

An opaque object is neither  apertureartificialblackclear imagesenergyluminous bodiesluminous objectsmirrorOpaqueopaque objectoppositePinhole camerareflectionShadowsstraight linetranslucenttransparent nor  apertureartificialblackclear imagesenergyluminous bodiesluminous objectsmirrorOpaqueopaque objectoppositePinhole camerareflectionShadowsstraight linetranslucenttransparent.

 apertureartificialblackclear imagesenergyluminous bodiesluminous objectsmirrorOpaqueopaque objectoppositePinhole camerareflectionShadowsstraight linetranslucenttransparent are formed when an opaque object comes in the path of light.

 apertureartificialblackclear imagesenergyluminous bodiesluminous objectsmirrorOpaqueopaque objectoppositePinhole camerareflectionShadowsstraight linetranslucenttransparent can be made with simple materials and can be used to image the Sun and brightly lit objects.

Light travels in  apertureartificialblackclear imagesenergyluminous bodiesluminous objectsmirrorOpaqueopaque objectoppositePinhole camerareflectionShadowsstraight linetranslucenttransparent.

Mirror reflection gives us  apertureartificialblackclear imagesenergyluminous bodiesluminous objectsmirrorOpaqueopaque objectoppositePinhole camerareflectionShadowsstraight linetranslucenttransparent.

 apertureartificialblackclear imagesenergyluminous bodiesluminous objectsmirrorOpaqueopaque objectoppositePinhole camerareflectionShadowsstraight linetranslucenttransparent objects do not allow light to pass through them.

 apertureartificialblackclear imagesenergyluminous bodiesluminous objectsmirrorOpaqueopaque objectoppositePinhole camerareflectionShadowsstraight linetranslucenttransparent objects allow light to pass through them and we can see through these objects clearly.

 apertureartificialblackclear imagesenergyluminous bodiesluminous objectsmirrorOpaqueopaque objectoppositePinhole camerareflectionShadowsstraight linetranslucenttransparent objects allow light to pass through them partially.

A  apertureartificialblackclear imagesenergyluminous bodiesluminous objectsmirrorOpaqueopaque objectoppositePinhole camerareflectionShadowsstraight linetranslucenttransparent changes the direction of light that falls on it.

A  apertureartificialblackclear imagesenergyluminous bodiesluminous objectsmirrorOpaqueopaque objectoppositePinhole camerareflectionShadowsstraight linetranslucenttransparent is a simple camera without a lens but with a tiny aperture, a effectively a light-proof box with a small hole in one side.

Light from a scene passes through the  apertureartificialblackclear imagesenergyluminous bodiesluminous objectsmirrorOpaqueopaque objectoppositePinhole camerareflectionShadowsstraight linetranslucenttransparent and projects an inverted image on the  apertureartificialblackclear imagesenergyluminous bodiesluminous objectsmirrorOpaqueopaque objectoppositePinhole camerareflectionShadowsstraight linetranslucenttransparent side of the box, which is known as the camera obscura effect.

Light is a form of  apertureartificialblackclear imagesenergyluminous bodiesluminous objectsmirrorOpaqueopaque objectoppositePinhole camerareflectionShadowsstraight linetranslucenttransparent.

All bodies which emit light energy by themselves are called  apertureartificialblackclear imagesenergyluminous bodiesluminous objectsmirrorOpaqueopaque objectoppositePinhole camerareflectionShadowsstraight linetranslucenttransparent.

A glowing electric bulb is an example of  apertureartificialblackclear imagesenergyluminous bodiesluminous objectsmirrorOpaqueopaque objectoppositePinhole camerareflectionShadowsstraight linetranslucenttransparent source of light.

Any polished surface from which regular reflection takes place is called a  apertureartificialblackclear imagesenergyluminous bodiesluminous objectsmirrorOpaqueopaque objectoppositePinhole camerareflectionShadowsstraight linetranslucenttransparent.

The shadow of a coloured object is  apertureartificialblackclear imagesenergyluminous bodiesluminous objectsmirrorOpaqueopaque objectoppositePinhole camerareflectionShadowsstraight linetranslucenttransparent.

The image formed by a mirror is due to  apertureartificialblackclear imagesenergyluminous bodiesluminous objectsmirrorOpaqueopaque objectoppositePinhole camerareflectionShadowsstraight linetranslucenttransparent of light.
