A beaker containing liquid is placed on a table, underneath a microscope with can be moved along a vertical scale. The microscope is focused, through the liquid into a mark on the table when the reading on the scale is a. it is next focused on the upper surface of the liquid and the reading is b. More liquid is added and the observations are repeated. The corresponding readings are c and d. The refractive index of the liquid is

Light of wavelengthlambda = 500 nm falls on two narrow slits placed a distance d = 50 xx 10^-4 cm apart, at an angle phi= 30^@ relative to the slits as shown in figure. On the lower slit a transparent slab of thickness 0.1 mm and refractive index 3/2 is placed. The interference pattern is observed at a distance D=2m from the slits. Then, calculate

A thin biconvex lens of refractive index 3/2 is placed on a horizontal plane mirror as shown. The space between the lens and the mirror is then filled with water of refractive index 4/3. It is found that when a point object is placed 15cm above the lens on its principal axis, the object coincides with its own images. On representing with another liquid, the object and the image again coincide at a distance 25cm from the lens
