Q98 / 180 · AIIMS 2001 · Physics

If red light is replaced by white light then width of diffraction pattern will

A
increases
B
decreases
Correct answer
C
a central white band is obtained
D
10 effect.

Solution

Since white light is not monochromatic, so we obtain a central white bond instead of getting fringes or a diffraction pattern.

Hence, the correct answer is option: 'C'.
