3. Fig. 37-1 A snapshot of waves of frequency f and wavelength spreading out in all directions from point S 1 in all directions.

4. Fig. 37-12 (a) A snapshot of sinusoidal waves spreading out from two coherent sources S 1 and S 2. The sources are in phase. (b) Constructive and (c) destructive interference.

5. Fig. 37-3 The same as in Fig. 37-2(a) but with red antinodal curves superimposed (curves of maximum amplitude.)

6. Fig. 37-4 (a) Young’s experiment showing the interference of light passing through two slits. (b) Geometrical analysis. (c) Geometry when distance R > d.
