यंग के द्वि-स्लिट प्रयोग में, फ्रिंज की चौड़ाई 0.4 मिमी है। यदि इसकी ज्यामिति को बदले बिना पूरे उपकरण को 43 अपवर्तनांक वाले पानी में डुबो दिया जाए, तो नई फ्रिंज चौड़ाई होगी:

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?
