MCQ
The angular spread of central maximum, in the diffraction pattern, does not depend on ______.
- AThe distance between the slit and sources
- BWidth of slit
- CWavelength of light
- DFrequency of light
✓
Answer
- The distance between the slit and sources
Explanation:
Angular spread of central maxima $=(\theta)=\frac{\lambda}{\text{b}}$
Where $\lambda$ = wavelength of light
b = width of slit
⇒ Clearly, it does depends on the distance between slit and sources.
