Answer 2

The sundial is a device that has been used since ancient times to measure time.

• The sundial works by measuring the position of the shadow of an object that is exposed to the sun.
• As the sun moves across the sky, the sun rays falling on the object change direction and thus the shadow of the object changes size and position.
• The accuracy with which the sundial tells the time depends on the precision with which it is constructed. Its main drawback is that even when constructed with utmost precision, the sundial can only predict time with moderate accuracy.
• Another drawback of the sundial is that it is cumbersome to transport, given the fact that it is most commonly made of materials like granite and stone.
