General properties of waves — practice question
Fig. 7.1 illustrates a light ray undergoing refraction as it moves from air into glass. The labels include ray of light, normal, air, glass, and angles marked w, x, y and z.
(a(i))[1]
State which angle w, x, y or z is the angle of refraction.
(a(ii))[1]
State another example of a transverse wave.
(b(i))[2]
On Fig. 7.2, draw three wavefronts that have passed through the gap.
(b(ii))[1]
State the name of the effect in (b)(i).
