Take two plates A and B of same metal. Polish surface of A with black colour and surface of B with white colour. Take one electric heater and put polished black plate and white plate on vertical stand in such a way that polished black plate and white plate face the heater. Ensure that polished plates are equidistant from the heater. Fix one cork each with wax on the uncoated sides (back side) of the plates. Observe and comment which surface absorbs heat radiations more quickly; Black Plate Surface or White Plate Surface.

Sleek and polished plates ar dangerous radiators of warmth.
Explanation:
Optics is that the branch of physics that studies the behavior and properties of sunshine, as well as its interaction with matter and also the construction of devices that use or observe it.
Sleek and polished plates ar dangerous radiators of warmth. Therefore, the warmth dissipated by A is little, despite the fact that B being a black and rough plate could be a sensible absorbent material. Effectively the warmth returning to the left of the pellet P is smaller.
Black and rough plates ar sensible radiators of warmth. Therefore, plate (B2) radiates heat to a satisfactory level; but, the plate (A2), being sleek and polished, could be a poor absorbent material. Effectively, the warmth returning to the correct of P is additionally less.
