Light of wavelength 700 mm is incident on the face of a fused quarts prom at an angle of co.0* (with respect to the normal to the surface). The apex angle of the prism is co.0. Use the value of a from figure 35. to, to calculate the following angles, Figure 35.30 4at the angle of refraction at the first naface {b) the angle of incidence at the second surface () the angle of refraction at the soooad surface (d) the angle between the leacident and emerging roys
