The speed of the light that propagates through a medium is 1.24 x 10^6 ms-1. Calculate the refractive index of the medium. Given the speed of light in vacuum is 3.0 x 10^8 ms-1
(a)
What is the speed of light in a medium with refractive index of 1.47?
(a)
Diagram 1.1 shows a ray of light entering from air into water.
Based on Diagram 1.1 (i) ,
Compare the speed of light in water with the speed of light in air.
(a)
Diagram 1.1 shows a ray of light entering from air into water.
Based on Diagram 1.1,
If the water is replaced with liquid Y which is optically denser than water, state the change in direction of bending of light in the liquid Y.
(a)
Diagram 1.1 shows a ray of light entering from air into water.
Based on Diagram 1.1,
Name the phenomenon shown in Diagram 1.1.

Diagram 1.2 shows a coin at the base of the beaker which contains a liquid Z with the depth of 15 cm.
The observer found the image of the coin appears to be 4 cm from the base of the beaker.
(i) Calculate the refractive index of the liquid Z.
(a)
Diagram 1.2 shows a coin at the base of the beaker which contains a liquid Z with the depth of 15 cm.
The observer found the image of the coin appears to be 4 cm from the base of the beaker.
