In case of diffraction 1 if ' \(a\) ' is a slit width and 1 is the wavelength of the incident light, then the required condition for diffraction to take place is
- A \(\frac{a}{\lambda}=1000\)
- B \(\frac{a}{\lambda} \leq 1\)
- C \(a \ll 1\)
- D \(a \gg 1\)
Answer & Solution
Correct Answer
(B) \(\frac{a}{\lambda} \leq 1\)
Step-by-step Solution
Detailed explanation
Condition for diffraction is Slit width \(\leq\) wavelength of light \(\Rightarrow \mathrm{a} \leq \lambda \quad \therefore \frac{\mathrm{a}}{\lambda} \leq 1\)
