Interference of waves:
When two waves of similar amplitude and period traveling in the similar medium superpose, they reinforce each other at one point and cancel at others. This phenomenon is called as the interference of waves.

Dirac constant; Planck constant, modified form; hbar A sometimes more convenient form of the Planck constant, explained as hbar = h/(2 pi).
Defects of vision and their correction There is a simple relationship between the focal length F ,the object distance P and the image distance Q of a thin lens fig(1).
Correction of short sightedness To remove this defect a convex lens is used in front of eye.
