YDSE Central Maxima and Interference Energy Conservation – Rankers Physics

Young's Double Slit Experiment: Practice Problem & Solution

Assertion (A): In YDSE central maxima means the maxima formed with zero optical path difference. It may be formed anywhere on the screen. Reason (R): In an interference pattern, whatever energy disappears at the minimum, appears at the maximum.  
Both (A) & (R) are true and the (R) is the correct explanation of the (A)
Both (A) & (R) are true but the (R) is not the correct explanation of the (A)
(A) is true but (R) is false
Both (A) and (R) are false

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Young's Double Slit Experiment. Understanding the underlying formula is key to arriving at the correct answer below:

Both Assertion (A) and Reason (R) are true statements. Central maxima is indeed defined by zero path difference, and its location can be shifted. Interference redistributes energy, meaning energy is conserved. However, (R) does not explain the definition or position of central maxima in (A).
