Question
Solids and liquids both expand on heating. The density of substance decreases on expanding according to the relation
when a solid is submerged in a liquid, liquid exerts an upward force on solid which is equal to the weight of liquid displaced by submerged part of solid. Solid will float or sink depends on relative densities of solid and liquid A cubical block of solid floats in a liquid with half of its volume submerged in liquid as shown in figure (at temperature T)
The relation between densities of solid and liquid at temperature T is
The correct answer is:

A slab of high quality flat glass, with parallel faces, is placed in the path of a parallel light beam before it is focussed to a spot by a lens. The glass is rotated slightly back and forth from the vertical orientation, about an axis out of the page as shown in the figure. According to ray optics the effect on the focussed spot is:
