Question

No. Of standing waves in 3rd orbit

Answer 1

Explanation:

the number of waves in 3rd orbit of H atom are 3.

Answer 2

Answer:

   A standing wave has the following characteristic :

   Standing waves can be transverse or longitudinal. In case of longitudinal stationary waves nodes are points of maximum pressure (minimum displacement) because phase difference of π/2 between pressure wave and displacement wave. And antinodal points have minimum pressure (maximum displacement). In organ pipes longitudinal stationary waves are obtained.

In case of longitudinal stationary waves nodes are points of maximum pressure (minimum displacement) because phase difference of π/2 between pressure wave and displacement wave. And antinodal points have minimum pressure (maximum displacement). In organ pipes longitudinal stationary waves are obtained. In standing wave if the amplitude of component waves are not equal then. Amin≠ 0 i.e. node will not be permanently at rest and so some energy will pass across the node and wave will be partially standing.
