15. Consider the two light patterns shown in the figure Which of the following statements is true? Center of the pattern Pattern A Pattern B 10 11 12 13 14 15 16 17 18 19 20 21 ruler A. Pattern A is a action pattern from a single slit experiment; Pattern B is an interference pattern from a double slit experiment. B. Pattern A is an interference pattern from a double slit experiment; Pattern B is a diffraction pattern from a single slit experiment C. Pattern A can either be a diffraction pattern from a single slit experiment or an interference pattern from a double slit experiment. D. Pattern B can either be a action pattern from a single slit exerperiment or an interference pattern from a double slit experiment. E. None of the above.

Explanation / Answer

first we need to know which pattern is for single slit and which pattern for double slit.

since we know that in double slit the intensity or maxiam and minima are situated at some constant same distance which is Y = m *lambda *d/D

so distance between any two maxima and minimum remains same which is the the only one pattern

which is A pattern in the question

so A is for the double slit

in single slit central maxima is wider than any other maxima.

Thanks!!!
