Question
A standing wave of time period T is set up in a string clamped between two rigid supports. At t = 0 antinode is at its maximum displacement 2A.
Options
A.The energy density of a node is equal to energy density of an antinode for the first time at t = T / 4.
B.The energy density of node and antinode becomes equal after T/2 second.
C.The displacement of the particle at antinode at t = 
is √2 A
is √2 AD.The displacement of the particle at node is zero
Solution
Equation of SHM of particle who is at antinode is y = 2Asin 
t at time t = 
y = 2A sin 
= √2A ; Displacement of particle at note is always zero.
t at time t = y = 2A sin = √2A ; Displacement of particle at note is always zero.Create a free account to view solution
