Consider the following statements in case of Young's double slit experiment.
(1) A slit \(S\) is necessary if we use an ordinary extended source of light.
(2) A slit \(S\) is not needed if we use an ordinary but well collimated beam of light.
(3) A slit \(S\) is not needed if we use a spatially coherent source of light.
Which of the above statements are correct?
- A (1), (2) and (3)
- B (1) and (2)
- C (2) and (3)
- D (1) and (3)
Answer & Solution
Correct Answer
(D) (1) and (3)
Step-by-step Solution
Detailed explanation
In the case of Young's double slit experiment. A slit \(S\) is necessary if we use an ordinary extended source of light and \(A\) slit \(S\) is not needed if we use a spatially coherent source of light.
