समजा दोन रेखाछिद्रांच्या मधून पार होणाऱ्या प्रकाशाची तीव्रता I1 आणि I2 आहे. δ अवस्थांतर असणाऱ्या बिंदूवरील तीव्रता देता येईल,
\({I} = {I_1} + {I_2} + 2{√ {{I_1}{I_2}}}\; {cos \; {\delta}}\)
वरील समीकरण महत्तमावरील तीव्रता दर्शविते (δ = 0) आणि लघुत्तम (δ = π)
\({I_{max}} = {I_1} + {I_2} + 2{√ {{I_1}{I_2}}}\)
\({I_{min}} = {I_1} + {I_2} + 2{√ {{I_1}{I_2}}}\)
जेव्हा रेखाछिद्र समान रुंदीचे असतात,
जेव्हा एका रेखाछिद्राची रुंदी दुप्पट केल्यास,
आता महत्तम आणि लघुत्तम तीव्रता असतील
Imax = (3+2√2) I0 = 5.83 I0;
Imin = (3 - 2√2) I0 = 0.17 I0;
वरील मूल्यावरून, हे स्पष्ट आहे की महत्तम आणि लघुत्तम दोघांची तीव्रता वाढते.
