Question

short note on sundial​

Answer 1

A sundial is a device that tells the time of day when there is sunlight by the apparent position of the Sun in the sky. The style is the time-telling edge of the gnomon, though a single point or nodus may be used. The gnomon casts a broad shadow; the shadow of the style shows the time.
