2. When light travels from one medium to another of different densities thereby causing the speed of light to be slowed down;
a. What is this phenomenon called?
b. Draw a well labelled diagram showing refraction between air and water.
c. The real depth of a coin in a swimming pool is12 m. If the refractive index of water is 4/3, calculate the apparent
depth of the swimming pool.
d. The speed of light in air is 300000000 m/s. If the refractive index of diamond is 2.4, calculate the speed of light in
diamond.
