37 pathway of light through the eye diagram
Earlier in this lesson, the following diagram was shown to illustrate the path of light from an object to mirror to an eye. In this diagram five incident rays are drawn along with their corresponding reflected rays. Each ray intersects at the image location and then diverges to the eye of an observer. Q. Examine the diagram showing an incoming ray of light labeled X traveling through air, making contact with a sheet of glass and the two resulting rays of light labeled Y and Z.Which statement correctly describes the behaviors of the rays of light?
In this diagram the angle of incidence, the angle of emergence and the angle of deviation respectively are (select the correct option) X, R and T; Y, Q and T; X, Q and P; Y, Q and P [1 mark] [CBSE 2014] Study the following diagrams in which the path of a ray of light passing through a glass prism as traced by four students P, Q, R and S is shown:
Pathway of light through the eye diagram
Q 51 – A student is observing the diagram showing the path of a ray of light passing through a glass prism. He would find that for all angles of incidence the ray of light bends: (а) towards the normal, while entering into the prism and away from the normal while emerging out of the prism. (b) away from the normal while entering into the prism and towards the normal while emerging out of ...

Pathway of light through the eye diagram. 1. Part of the eye which controls the light entering is called (a) iris (b) cornea (c) lens (d) retina. Soln: Answer is (a) iris. Explanation: Iris is a dark muscular structure exists behind the cornea. Its function is to control the entry of light. 2. We can see a non-luminous object when light: (a) emitted by the object falls on the eye. Draw a ray diagram showing the path of a ray of light entering through a triangular glass prism. Deduce the expression for the refractive index of glass prism in terms of the angle of minimum deviation and angle of the prism. (Comptt. All India 2012) Answer: A ray PQ is incident on the face AB of prism at ∠i and effected along QR at ∠r. The first thing light encounters when it enters the eye is the cornea, a protective clear covering over the pupil and iris. The cornea bends the light and begins to form an image. Light passes from the cornea to the pupil, the dark circle in the centre of the iris, which is the coloured portion of the eye. It is mainly responsible for vision, differentiation of colour (the human eye can differentiate approximately 10 – 12 million colours) and maintaining the biological clock of the human body. The human eye can be compared to a camera as both works by gathering, focusing and transmitting the light through the lens for creating an image of an ...
