1. Yes, the law of conservation of energy is obeyed in the interference of light. While energy is redistributed between constructive and destructive interference regions, the total energy across the entire interference pattern remains constant. No energy is created or destroyed in the process. For moreRead more

  2. For two light sources to be coherent, they must meet the following conditions: 1. They must have a constant phase relationship, meaning the phase difference between them remains fixed over time.They must emit light of the same frequency (monochromatic light). 2. They must have a constant amplitude rRead more

    For two light sources to be coherent, they must meet the following conditions:
    1. They must have a constant phase relationship, meaning the phase difference between them remains fixed over time.They must emit light of the same frequency (monochromatic light).
    2. They must have a constant amplitude ratio, ensuring uniform intensity over time for stable interference patterns.

  3. (i) No Chromatic Aberration: Reflecting telescopes avoid color distortions (chromatic aberration) since mirrors do not refract light. (ii) Larger Apertures: Mirrors can be made much larger than lenses, allowing for more light gathering. (iii) No Lens Sagging: Mirrors support their own weight, unlikeRead more

    (iii) No Lens Sagging: Mirrors support their own weight, unlike lenses, which can sag and distort the image due to gravity.

  4. 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.

  5. 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
