1. Light travels through glass of refractive index 1.5 with a speed V. calculate the value of V. (speed of light in air = 3.0 x 108

 m/s).

2. A ray of light incident on the surface of a glass prism is observed to behave as represented in the diagram in Fig. 6 Explain this observation.

3. A small object lies at the bottom of a water pond at a depth of 1.2m. Given that the refractive index of water is 1.3, determine the apparent depth of the object. (Give your answers to 1 decimal place).
