When a ray of light enters from one medium to another, then which of the following does not change?

When a ray of light enters from one medium to another then its velocity in second medium becomes doubled. The maximum value of angle of incidence so that total internal reflection may not take place will be

The change in ……………… of light while going from one medium to another is called refraction.

When a ray of light enters from one medium to another having different optical densities, it bends. Why does this phenomenon occur ?

Draw a labelled ray diagram to illustrate (a) critical angle (b) total internal reflection for a ray of light moving from one medium to another.

Consider a ray of light passing from one medium to another. If the angle of refraction is less than the angle of incidence, will the speed of light in the second medium be less or more than that in the first medium?

The phenomenon in which when a ray of light travels from one medium to another, bends at the boundary between the two medium
