IB Physics SL C.3.11 Resolution and Rayleigh Criterion Question Bank

Practise IB Physics SL C.3.11 by applying the Rayleigh criterion and diffraction limits to eyes, telescopes, cameras and other apertures.

[Maximum number: 2]

This question is about diffraction and resolution.

Monochromatic light is incident normally on a single narrow slit and gives rise to a diffraction pattern on a screen.

Figure for Question C.3.11—Resolution and Rayleigh criterion question 1 — IB Physics SL

Two lamps emit light of wavelength 620 nm . The lights are observed through a circular aperture of diameter 1.5 mm from a distance of 850 m . Calculate the minimum distance between the lamps so that they are resolved.
