In a Young's double-slit experimental set-up with slit separation 0.6 mm a beam of light consisting of two wavelengths 440 nm and 660 nm is used to obtain interference pattern on a screen kept 1.5 m in front of the slits. Find the least distance of the point from the central maximum where the bright fringes due to both the wavelengths coincide. 12th Physics CBSE PYQ 2026 12th Physics CBSE PYQ 2025 CBSE 12th Physics Solution Class 12th CBSE Physics Class XII CBSE Physics CBSE 12th PYQ 2026 Physics CBSE 12th PYQ 2025 Physics CBSE 12th PYQ 2024 Physics CBSE with PYQ 2023 2025 2026 Physics 12th PYQ CBSE Solution Physics 12th CBSE sample paper solution Physics Class 12th CBSE Physics Previous year questions solution Class 12th CBSE Physics Previous year questions solution CBSE Maths 12th PYQ Solution Physics #cbseboard #cbse #cbseclass12 #maths #physics #study #boardexam #class12th #examination #education #science #physics
