In young's double slit experiment with a source of light of wavelength

6320\,\mathop {\text{A}}\limits^ \circ

, the first maxima will occur when

View answer and explanation

Correct option: C

Path difference is

6320\,\mathop {\text{A}}\limits^ \circ

Option C (Path difference is

6320\,\mathop {\text{A}}\limits^ \circ

) is correct because the first maxima occurs when the path difference is equal to one wavelength.
