ON21 P23 Q5 Double Slit Interference Graph | Oct/Nov 2021 | Cambridge A Level 9702 Physics
9702/23/O/N/21: (a) For a progressive wave on a stretched string, state what is meant by amplitude.

(b) Light from a laser has a wavelength of 690 nm in a vacuum. Calculate the period of the light wave.
(c) A two-source interference experiment uses the arrangement shown in Fig. 5.1. Light from a laser is incident normally on a double slit. A screen is parallel to the double slit. Interference fringes are seen on the screen at distance D from the double slit. The separation of the centres of the slits is a. The light has wavelength λ. The separation x of the centres of adjacent bright fringes is measured for different values of distance D. The variation with D of x is shown in Fig. 5.2. The gradient of the graph is G.

(i) Determine an expression, in terms of G and λ, for the separation a of the slits.
(ii) The experiment is repeated with slits of separation 2a. The wavelength of the light is unchanged. On Fig. 5.2, sketch a graph to show the results of this experiment.
