What are nodes and internodes?

What are nodes of Ranvier?

Two progressive transverse waves given by y_(1) =0.007 sinpi ( 12x- 500 t ) and y _(2) = 0.07 sin pi ( 12x+500t) travelling along a stretched string from nodes and antinodes . What is the displacement at the (a) nodes (b) antinodes ? What is the wavelength of the standing wave ?

A taut string fixed at both ends vibrates in n^(th) overtone. The separation between adjacent node and antinode is equal to 'd'. Then string length is

What is the distance between a node and an antinode in a stationary wave ?

What do you understand by the terms 'node' and 'antinode ' ?

The hydrogen like species Li^(2+) is in a spherically symmetric state S_(1) with one radial node. Upon absorbinf light the ion undergoes transition to a state S_(2) The state S_(2) has one radial node and its energy is equal to the ground state energy of the hydrogen atom. The state S_(1) is
