Light of wavelength 700 nm is incident on the face of a fused quartz prism at an angle of 68.0" (with respect to the normal to the surface). The apex angle of the prism is 60.0* Use the value of n from Figure 35.20, to calculate the following angles Gengis ** IM IM 5 1.50 LAB LAB Merde Feed quan 400 500 600 700 Lam Figure 35.20 (a) the angle of refraction at the first surface (b) the angle of incidence at the second surface (c) the angle of refraction at the second surface (d) the angle between the incident and emerging rays
