. A converging thin lens forms an image (at a distance 20 cm in front of the lens) of an object which is 10 cm in front of the lens. What is the focal length of the lens in units of cm? (1) 20 (2) 10 (3) 5 (4) 15 (5) 40 . Light that is unpolarized passes through two polarizing lters, one after the other. The intensity of the light after the rst lter is ID. The second lter has its transmission axis at a 45 angle with respect to the transmission axis of the rst lter. What fraction of the light intensity In passes through the second lter? (1) 0.5 (2) 0.33 (3) 0.75 (4) 1.0 (5) 0.25 . Parallel light rays of wavelength 500 nm 500 x 10'9m from the left pass - - - through a single slit of width 'a' and cre(ate the diffradtion pattern shown Slngle Slit lefractlon shown on a screen 'L' away from the slit (drawing is not to scale 'L' is much larger than either 'a' or 'y2'). The angle 6 shown is the angle of the second minimum (dark fringe), which is a distance 'yz' above the center of the bright peak in the middle. If L=1 m and y2=1 cm, what is the width of the slit in units of 106m? g __""' y, ) 1 100 " 2 l 3 50 4 0.5 5 10 I. . Consider two lenses, A and B. Lens A has a diameter of 3 cm, and lens B has a diameter of 3.5 cm. What is the ratio of the light intensity)r passed by the two lenses, I A /I B? The lenses are both smaller than the area covered by the incoming light rays. (1) 1 (2) 1.36 (3) 0.86 (4) 1.17 (5) 0.73 White light falls normally on a diffraction grating having 2000 lines/ cm. At what angle (in degrees) will red light [A = 650 mn] be Observed in the thirdorder spectrum? (1) 23 (2) 3.7 (3) 7.5 (4) 11.2 (5) none of these The distance between the eyepiece and the objective lens of a compound microscope is 22 cm. The focal length of the objective is 0.50 cm and that of the eyepiece is 1.5 cm. What is the overall magnication of this microscope? (1) 733 (2) 500 (3) 667 (4) 844 (5) 345
