Questions Related to coherence

True & False Statement Type
$S _1$ : In an elastic collision initial and final K.E. of system will be same.
$S _2$ : In a pure L-C Circuit average energy stored in capacitor is zero.
$S _3$ : In YDSE coherent sources are formed by division of wave front method.
$S _4$ : If a physical Quantity is quantized then it must be integral multiple of its lowest value.

  2. TTFT

  3. FTFT

  4. TFTT

Show answer
Correct Option: D
Explanation:

S1: In an elastic collision the kinetic energy is conserved so the initial and final K.E. of system will be same. (T)
S2: In a pure L-C Circuit average energy stored in capacitor always oscillate between a maximum and a minimum. So not zero always.(F)
S3:In YDSE coherent sources are formed by division of wavefront method from a single source of light. (T)
S4: If a physical Quantity is quantized then it will be the integral multiple of its lowest value (T)
