  • Figure 10.2 shows a standard two-slit arrangement with slits S_1 S_2 P_1 P_2 are the two minima points on either side of P (Fig 10.2) At P_ 2 on the screen

Figure 10.2 shows a standard two-slit arrangement with slits S1, S2. P1, and P2 are the two minima points on either side of P (Fig. 10.2). At P2 on the screen, there is a hole, and behind P2 is a second 2- slit arrangement with slits S3, S4, and a second screen behind them.

 

 

A. There would be no interference pattern on the second screen but it would be lighted.
B. The second screen would be totally dark.
C. There would be a single bright point on the second screen.
D. There would be a regular two-slit pattern on the second screen

Answers (1)

The correct answer is the option d

Explanation:-

The wavefront is the plane where every point on a given wavefront is the source of disturbance which are known as secondary wavelets. The second screen will still display a regular two-slit interference pattern because the light that reaches the second screen is still coherent and exhibits interference behavior.

The wavefront emitted by a narrow source is divided into two parts reflection, refraction, or diffraction. The coherent sources so obtained are imaginary.
