A single slit Fraunhoffer diffraction pattern is formed with white light. For what wavelength of light the third secondary maximum in the diffraction pattern coincides with the second secondary maximum in the pattern for red light of wavelength

6500\,\mathop \mathrm{A}\limits^ \circ

View answer and explanation

Correct option: C

4642.8\,\mathop \mathrm{A}\limits^ \circ

Option C (

4642.8\mathop \mathrm{A}\limits^ \circ

) is correct because the position of the maxima in a single-slit diffraction pattern depends on the wavelength.
