It is known that the angle of refraction from normal isn’t equal to the angle of the incident light from normal (φa = φr) Correct Answer False

It is known that the angle of reflection from normal is equal to the angle of the incident light from normal (φa = φr). It’s also known that the sin φa/sin φb, = n of the transparent material.

The human eye is a complex part of the body that is used for seeing. Eyes enable people to perform daily tasks and to learn about the world that surrounds them. Sight, or vision, is a rapidly occurring process that involves continuous interaction between the eye, the nervous system, and the brain. When someone looks at an object, what he really sees is the light reflected from the object. This reflected light passes through the lens and falls on the retina of the eye. Here the light induces nerve impulses that travel through the optic nerve to the brain and then over other nerves to muscles and glands.
The eye is similar to a television camera. Both the eye and the television camera convert light energy to electrical energy. The eye converts light to nerve impulses that are interpreted by the brain as the sense perception called sight. A television camera converts light to electronic signals that are broadcast and transformed into light images in a television receiver. It is wonderful that human eyes blink an average of once every six seconds. This washes the eye with the salty secretion from the tear or lachrymal glands. Each tear gland is about the size and shape of an almond. These glands are situated behind the upper eyelid at the outer corner of the eye. After passing over the eye, the liquid from the gland is drained into the nose through the tear duct at the inner corner of the eye. The sense perception that the brain releases after the eye converts light to nerve impulses is known as
__________ means that when light travels from a material of less index of refraction to a material of higher index of refraction, the light is bent towards the normal.
If a monochromatic ray of light is incident on a glass surface at its polarising angle. What is the angle of refraction of the light in that medium?
A light is incident on a glass slab. The angle of incidence is 54° while the angle of refraction is 30°. What will be the speed of light in the glass slab?
The green light only ever goes on when tank A is full and tank C isn't empty. The red light is always on unless either tank A isn't Full or tank B is empty. Given that the green light is on, we can conclude all of the following EXCEPT---
