To Burn a Candle in Glass full of water

Our Objective

To burn a candle in a glass full of water. 

 

The Theory 

Light 

Light is a kind of energy or can be said it is an electromagnetic radiation which is visible to the human eye. 

  • Incident light  

The incident light comes from the source and strikes the object. 

  • Reflected light  

Refracted light is the light that then bounces back off the object. 

          When you look at a mirror and see your face reflected, what's actually going on?  
 

Yes, it is the light is hitting your face and bouncing into the mirror. 

 

From the above image we can observe a candle is burning in a glass full of water how? 

A polished transparent material like plane glass, which can reflect a small amount of incident light, so we get an image of both the candle and water on the same plane of glass. An illusion is created by precisely positioning and aligning up two things that would not normally fit into one another. Both the glass of water behind it and the candle in front create an image in the plane of the glass sheet. This illusion is created by aligning these two images so that they perfectly overlap with one another. 

The glass plate partially acts as a plane mirror. Therefore, the image of the candle is at the same distance behind the glass plate as that of the lighted candle in front of it.  

 

Learning Outcomes  

  • Students can understand the definitions of light, reflected, and incident light. 
  • Students can understand the concept of the illusion of image. 
  • Students are able to perform the experiment better in the real lab after experiencing it in the virtual lab.
