Conditions of diffraction is
- A \(\frac{a}{\lambda} \neq 1\)
- B \(\frac{a}{\lambda}>>1\)
- C \(\frac{a}{\lambda}< < 1\)
- D \(\frac{a}{\lambda} \leq 1\)
Answer & Solution
Correct Answer
(D) \(\frac{a}{\lambda} \leq 1\)
Step-by-step Solution
Detailed explanation
For diffraction, the width \(a\) of slit must be less than or comparable to wavelength of light used. i.e., \[ \frac{a}{\lambda} \leq 1 \]
