Gce Model Questions Vol1 2024 Physics Question 5
Practice objective / multiple choice question 5 from the 2024 Gce Model Questions Vol1 Physics examination.
Two narrow slits, each of width \(a=0.02\ \text{mm}\), are separated by a centre‑to‑centre distance \(d=0.30\ \text{mm}\). They are illuminated by monochromatic light of wavelength \(\lambda=600\ \text{nm}\). A converging lens of focal length \(f=0.5\ \text{m}\) is placed after the slits so that the interference‑diffraction pattern is observed in the focal plane of the lens. Find the linear separation between the two outermost bright fringes that are still visible within the central single‑slit diffraction envelope.
