A parallel beam of monochromatic light falls normally on a narrow slit of width 'a' to produce a diffraction pattern on the screen placed parallel to the plane of the slit. Use Huygens' principle to explain that (i) the central bright maxima is twice as wide as the other maxima. (ii) the intensity falls as we move to successive maxima away from the centre of on either side. (Delhi 2014C) Sir please solve this problem
Sodium light has two wavelengths λ₁ = 589 nm and 2.2 = 589.6 nm. As the path difference increases, when is the visibility of the fringes minimum ? [NCERT] Sir please solve this problem
I completed my 12th in 2024 by State Board of Rajasthan. I appeared in JEE ADVANCED 2024 for the first time but i didn't get qualified. So, I decided to take a drop but due to some health and study issues, I am not prepared for JEE ADVANCED 2025. My query is that if I give 12th exam again by NIOS or by any other state board, then, will I become eligible for JEE ADVANCED 2026?
