1 b 2 Өь Нө = 90° пь 3 na Өa ec > Ө 4 a Р Figure 2

1) Use Snell's Law (na sin(theta)a = nb sin(theta)b) to explain why (theta)b is greater than (theta)a in Fig.2

2) In Fig. 2, if we increase the index nb but keep nb < na, should the value of (theta)c increase or decrease? Give your reasoning.

3) Does total internal reflection occur if the refraction of light is passing from ait into water? Why?

2. Use Snell's law (n, sin = n, sine,) to explain why , is greater than 0 in Fig. 2. Total Internal Reflection When light passes from a medium of large refractive index into one of small refractive index --- for example, from water to air --- the refracted ray bends away from the surface normal, as shown in Fig. 2. As the angle of incidence increases, the angle of refraction also increases. When the angle of incidence reaches a...
