Quantum Nature of Light with Young’s Double-Slit Experiment
1. Which phenomenon is illustrated when sand particles pass through a narrow slit and form a spread-out pattern?
2. In single-slit diffraction, the condition for the mth dark fringe (minimum) is:
3. In Young's double-slit experiment, fringe width increases when:
4. What happens to the interference pattern in the electron double-slit experiment when the path of electrons is observed?
5. The observation that electrons show interference even when fired one at a time supports the concept of:
6. In Young's double-slit experiment, fringe width β = λD/d. If slit separation d is halved, what happens to the fringe width?
7. Which principle states that every point on a wavefront acts as a source of secondary wavelets?
8. What type of interference produces bright fringes in Young's double-slit experiment?
9. De Broglie's hypothesis states that matter particles have an associated:
10. In the electron double-slit experiment, before enough electrons are collected, the screen shows:
