Question

Yellow light is used in a single slit diffraction experiment with slit width of $0.6mm$. If yellow light is replaced by X-rays, then the observed pattern will reveal.

• A. That the central maximum is narrower
• B. More number of fringes
• C. Less number of fringes
• D. No diffraction pattern

Answer 1

The correct option is D No diffraction pattern

No diffraction pattern will be observed because

$\left(i\right)$ X-rays cannot be seen through naked eye.

$\left(ii\right)$ If X-rays are not of comparable size to diffract for a slit width of $0.6$mm.
