The working of an optical fiber is based on the principle of total internal reflection. When light enters the fiber at a certain angle, it is continuously reflected inside the core due to the difference in refractive indices between the core and the cladding. This allows light to travel long distancRead more
The working of an optical fiber is based on the principle of total internal reflection. When light enters the fiber at a certain angle, it is continuously reflected inside the core due to the difference in refractive indices between the core and the cladding. This allows light to travel long distances with minimal loss, even around bends.
The angular width of the principal maximum in a single-slit diffraction pattern is inversely proportional to the slit width. As the slit width decreases, the angular width increases, spreading the diffraction pattern more widely on the screen. For more visit here: https://www.tiwariacademy.com/ncertRead more

If the monochromatic source in Young's double-slit experiment is replaced by white light, the central fringe remains white, while the surrounding fringes appear as overlapping colored spectra.

If the monochromatic source in Young’s double-slit experiment is replaced by white light, the central fringe remains white, while the surrounding fringes appear as overlapping colored spectra. Each color interferes differently due to varying wavelengths, leading to a sequence of rainbow-like fringes. Beyond a few fringes, the colors overlap completely, producing a uniform white light pattern.
Reducing the slit width to half doubles the angular width of the central maxima, making it wider. However, the intensity of the central maxima decreases significantly because the light passing through the slit is reduced, causing less energy to be distributed across the pattern.

A parallel beam of monochromatic light falls normally on a single narrow slit. How does the angular width of the principal maximum in the resulting diffraction pattern depend on width of the slit?
