Questions and Answers
What is the main difference between interference and diffraction?
What is the main difference between interference and diffraction?
- Interference involves interaction between wave fronts from different sources, while diffraction involves interaction between secondary wavelets from the same wave front. (correct)
- In diffraction, all maxima have the same intensity unlike interference patterns.
- Interference involves interaction between secondary wavelets, while diffraction involves interaction between wave fronts.
- In interference, the regions of minimum intensity are not perfectly dark, while in diffraction, they are.
What distinguishes the width of fringes in interference patterns from those in diffraction patterns?
What distinguishes the width of fringes in interference patterns from those in diffraction patterns?
- Interference patterns always have perfectly dark regions, which is not the case in diffraction patterns.
- Interference patterns have varying fringe widths, while diffraction patterns have uniform fringe widths.
- The fringe width is never equal in interference patterns, unlike diffraction patterns.
- The fringe width is sometimes uniform in interference patterns, but never in diffraction patterns. (correct)
How do the intensities of maxima differ in interference and diffraction patterns?
How do the intensities of maxima differ in interference and diffraction patterns?
- Diffraction patterns have perfectly dark regions unlike interference patterns.
- Interference patterns have varying intensity for maxima, unlike diffraction patterns.
- Maxima intensity is always significantly higher in diffraction patterns compared to interference patterns.
- In interference patterns, all maxima have the same intensity, while in diffraction patterns they vary. (correct)
