This is caused by a change in the speed of light .
Other than what??? Refraction will happen any time light passes from one material to another.
There will be refraction when light passes from one substance to the other (for example, from air to water), when the two substances have different indices of refraction, and when light passes the surface at an angle. In other cases, there is no refraction.
refraction
no. Energy is conserved.
Refraction occurs when light travels from one medium to another having different optical densities.
what is the meant by total internal reflection
Reflection, refraction, absorption.
Refraction is the phenomenon causes colors of visible light to be separated by a prism.

What is Refraction?? What is Refraction??
Total internal refraction happens when a light ray travel from a lighter medium to a denser medium. Ex. A light ray passing through a Prism.
