Name that part of the eye which is equivalent to the photographic film in a camera.

In the following item, passage consists of six sentences. The first and sixth sentence are given in the beginning as S_1 and S_6 . The middle four sentences in each have been jumbled up. These are labelled P, Q, R and S. You are required to find out the proper sequence of the four sentences and indicate your answer accordingly on the Answer Sheet. S_1 : If you want to film a scene in slow motion you run the camera twice as fast as usual, which sounds ridiculous but isn't. S_6 : On the screen, everything appears at half the speed at which the camera recorded it when it was filmed. P: If you are filming in slow motion, however, the camera runs at twice the normal speed, yet, in spite of this, the projector which shows the film will be run at the normal speed, and this means that the projector will show the film at half the speed at which it was photographed. Q : This is because the camera which took the pictures and the projector which shows them run at the same speed. R: When a film camera is running at normal speed, it takes twenty-four pictures a second. S: When the film is run through the film- projector in the camera twenty-four pictures a second appear on the screen. The proper sequence should be :

A point object O can move along vertical line AB as shown in figure . When image of the object is first visible to D then it is released at t=0 from rest from A . The time for which image is visible to D is :

A magnifying glass is used, as the object to be viewed can be brought closer to the eye than the normal near point. This results in.
