what is the differance between mirage and total internal reflection?????

Hi Anughraha!

 

Total internal reflection is an optical phenomenon which happens when a light ray strikes the interface between a denser medium and a rarer medium, at an angle greater than the critical angle. In this situation, all the lights striking the interface will reflect back to the first medium. Total internal reflection is the basic principle of optical fiber communication.

 

Mirage is caused by the total internal reflection between layers of different density in atmosphere.

Mirage is an optical phenomenon caused by the total internal reflection of light from distant objects. When light passes from cold air (denser) to hot air (rarer), it bends away from the normal and undergoes total internal reflection, thus causes an illusion to the observer that, light is coming from the ground.

 

Hope it helps!

Cheers!!
