Question
In stationary wave on string :-
Options
A.Strain is maximum at nodes
B.Strain is maximum at antinodes
C.Strain is minimum at nodes
D.Amplitude is zero at all the points
Solution
At nodes, 
is max. so strain is max. & zero at antinodes.
Amplitude is zero at nodes only.
is max. so strain is max. & zero at antinodes. Amplitude is zero at nodes only.
