This question has a paragraph followed by two statements, Statement – 1 and Statement – 2. Of the given four alternatives after the statements, choose the one that describes the statements.
A thin air film is formed by putting the convex surface of a plane-convex lens over a plane glass plate. With monochromatic light, this film gives an interference pattern due to light reflected from the top (convex) surface and the bottom (glass plate) surface of the film.
A thin air film is formed by putting the convex surface of a plane-convex lens over a plane glass plate. With monochromatic light, this film gives an interference pattern due to light reflected from the top (convex) surface and the bottom (glass plate) surface of the film.
Statement – 1 : When light reflects from the air-glass plate interface, the reflected wave suffers a phase change of π.
Statement – 2 : The centre of the interference pattern is dark.

Explanation of Statements
The scenario described involves a thin air film formed between a convex lens and a glass plate, where interference patterns arise from the reflection of monochromatic light.
Statement 1: Phase Change at Reflection
- When light reflects off a medium with a higher refractive index (like glass), it undergoes a phase change of π (180 degrees).
- In this case, light reflecting from the air-glass interface indeed experiences this phase change.
- Therefore, Statement 1 is true.
Statement 2: Center of Interference Pattern
- The interference pattern results from the superposition of light waves reflected from the top and bottom surfaces of the air film.
- With a phase change of π at the air-glass interface, the reflected waves from the top and bottom surfaces will interfere constructively or destructively depending on the path difference and the phase change.
- At the center of the film (where the path difference is minimal), the conditions typically lead to destructive interference, resulting in a dark center.
- Hence, Statement 2 is true.
Relationship Between Statements
- While both statements are true, Statement 2 does not directly explain Statement 1. The phase change is a separate phenomenon that contributes to the overall interference pattern but does not solely dictate the darkness of the center.
- Thus, Statement 2 is not the correct explanation of Statement 1.
Conclusion
The correct option is b): Statement 1 is true, Statement 2 is true, but Statement 2 is not the correct explanation of Statement 1.
