    The appearance of bright and dark fringes in an interference pattern does not violate the conservation of energy. Energy is redistributed, not lost. In regions of constructive interference (bright fringes), energy is concentrated, while in destructive interference (dark fringes), it is minimized. The total energy across the pattern remains constant, adhering to the principle of conservation of energy.

  2. 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.

  3. 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.

  4. The central maxima will have a larger angular width with red light because red light has a longer wavelength than blue light. The angular width of the central maxima is directly proportional to the wavelength of the light used. For more visit here: https://www.tiwariacademy.com/ncert-solutions/classRead more

  5. No, the reduction in speed of light when it enters a denser medium does not imply a reduction in energy. The energy of light depends on its frequency, which remains constant during refraction. Only the wavelength and speed change, conserving the light's energy. For more visit here: https://www.tiwarRead more
