Take CBT

Question

In the context of the path difference in Young's experiment, what does Δρ = P1 - P2 represent?
Options
A The difference in wavelength between the two slits.
B The difference in intensity of light from the two slits.
C The difference in the distance traveled by light from each slit to a point D on the screen.
Correct Answer
D The difference in the speed of light from the two slits.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Page 2 and 3 define Δρ = P1 - P2 as the path difference, specifically 'the difference Δρ in the path length of light coming from S1 and S2'. P1 and P2 represent the paths (distances) from S1 and S2 to point D respectively.

Hint

Relate P1 and P2 to the distances from the sources (slits) to the observation point.
