Types of Media

Types of Media

 

 

 

Luminous objects


Objects that emit light on their own are called luminous objects. The light emitted by luminous objects enables us to see things around us. Examples of luminous objects are a tubelight, the sun, a lit candle, glowing bulb, a bonfire and a lit torch.

 

Non-luminous objects


Objects that do not emit light on their own are called non–luminous objects. The light emitted by luminous objects falls on non-luminous objects, and then bounces back to our eye, which enables us to see non-luminous objects. Examples of non-luminous objects are the moon, a book, a pen, a wooden box, a cupboard and a chair.

 

 

Opaque objects


Objects through which we cannot see are called opaque objects. A medium that does not allow light to pass through it is called an opaque medium. Examples of opaque medium are a pencil box, a wooden screen, a book, a towel, a ceramic plate and chart paper.

 

Transparent objects


If we are able to see anything clearly through an object, then such an object is said to be a transparent object. A medium that allows all the light incident on it to pass through it is called a transparent medium. Examples of transparent objects are plain glass, a reading glass, a plastic scale, window panes, a soap bubble and pure water.

 

Translucent media


Objects that allow only a part of the light incident on them to pass through it are called translucent media. Examples of translucent media are a shower stall, smoked glass, sun glasses and butter paper. Light travels in a straight line, and its rays represent the path of light.

 

Summary

 

  1. Opaque objects do not allow light to pass through them.
  2. Transparent objects allow light to pass through them and we can see through these objects clearly .
  3. Translucent objects allow light to pass through them partially.
