What is the effect on the enterference fringes in a Young’s double-slitexperiment if monochromatic source is replaced by a source of whitr light?

When white light replaces monochromatic light, interference patterns of different colors overlap. The central fringe is white, as all colors align there. Closest fringes to the center are red, and farthest are blue-violet, as violet fringes are narrower and red ...

In a single-slit diffraction experiment, the width of the slit is reduced to half its original width. How would this affect the size and intensity of the central maxima?

On reducing the size of slit to one-half, the size of central maximum will be doubled and the intensity will become 1/4 th of its previous value. Class 12 Physics Chapter 10 Wave Optics Session 2024-2025.

For a given single-slit, the diffraction pattern is obtained on a fixed screen first by using red light and then with blue light. In which case, will the central maxima, in the observed diffraction pattern, have a larger angular width?

For blue light the angular width of central diffraction maximum is more than that for red light. Class 12 Physics Chapter 10 Wave Optics Session 2024-2025.

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?

For diffraction at a single-slit the angular width of the principal maximum is inversely proportion to the width of the slit i.e., angular width θα 1/a . Class 12 Physics Chapter 10 Wave Optics Session 2024-2025.

When light travels from a rarer to a denser medium, the speed of light decreases. Does the reduction in speed imply a reduction in the energy?

No, reduction in speed on passing from a rarer to a denser medium does not imply a reduction in energy of light because the frequency of light remains unchanged and the energy of a light photon depends only on its ...
