यंग के द्वि-स्लिट प्रयोग (Young's double slit experiment) में, पथ अंतर λ4 और λ3 (λ = प्रयुक्त प्रकाश की तरंगदैर्ध्य) के दो बिंदुओं पर तीव्रताएं क्रमशः I1 और I2 हैं। यदि I0 प्रत्येक व्यक्तिगत स्लिट द्वारा उत्पन्न तीव्रता को दर्शाता है, तो I1 + I2I0 किसके बराबर है?

In interference and diffraction, light energy is redistributed. If it reduces in one region (dark fringe), it increases in another region (bright fringe). A. As there is no net gain or loss of energy, these phenomena are consistent with the principle of conservation of energy. B. Diffraction and interference are characteristics exhibited only by light waves. Choose the correct option:

Two waves of intensity I and 4I produce a resultant intensity of 5I in an interference experiment. What is the phase difference between the two waves?
