Why does a light ray incident on a rectangular glass slab immersed in any medium emerges parallel to itself?
The glass slab is rectangular and both sides of the glass slab have the same medium. The light refracts in such a way that incident and emergent rays are parallel.
Why does not a light refracts at 90 degrees?
You mean that as light is incident normally. Here the angle of incidence will be 0. As per Snell's law sine of angle of incidence / sine of angle of refraction = refractive index So Sin i = mu * sin r As i=0 then r too has to be 0 as mu is not equal to 0 Hence no refraction becomes possible for a normally incident light ray
What colour refracts the most when a ray of light passes through a prism?
violet
The portion of a light ray that falls on a surface is?
The portion of a light ray that falls on a surface is incident ray.
What is difference between incident ray and a reflected ray?
A ray of light which strikes the surface is called incident ray and a surface which is reflected is called a reflected ray
What happens to a beam of light once it hits water?
The incident ray (the incoming light) hits the water and then the speed is slowed. It is called 'Refraction'. Which is the bending of light through a translucent or transparent object.

The ingoing ray of light?
The ingoing ray of light is the incident ray
What is the difference between incident ray and the reflected ray?
incident ray-the light ray striking a reflecting surface is called the incident ray. reflected ray-the light ray obtained after reflection from the surface, in the same medium in which the incident ray is travelling , is called the reflected ray.
What is the change of path of a light ray from air into glass?
it refracts closer to the medium
What colour refracts the most when a ray of light passes through a prism?
violet
A light ray hitting a mirror at an angle is reflected off at angle?
The angle between the incident ray and the mirror is equal to the angle between the reflected ray and the mirror.
What is the ray of light which strikes the surface?
incident ray
What effect does a convex lens have on light?
It refracts light twice, such that the overall effect is that the light is converged. A ray diagram will help understand this.
The portion of a light ray that falls on a surface is a?
The portion of a light ray that falls on a surface is incident ray.
The portion of a light ray that falls on a surface is?
The portion of a light ray that falls on a surface is incident ray.
