Q. In Young’s double-slit experiment, if one slit is closed,

यंग के डबल-स्लिट प्रयोग में, यदि एक स्लिट बंद है,

A
Bright fringes double
चमकीली झाँटें दोगुनी
B
No fringes are formed
कोई फ्रिंज नहीं बनता है
C
Only dark fringes remain
केवल अंधेरे किनारे ही बचे हैं
D
Intensity increases
तीव्रता बढ़ जाती है

Explanation

Interference requires two coherent sources. If one slit is closed, only a single wavefront reaches the screen, and hence no interference pattern (fringes) is formed.
