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?
Options
- A(1), (2) and (3)
- B(1) and (2)
- C(2) and (3)
- D(1) and (3)
Correct answer
D. (1) and (3)
Step-by-step solution
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.
