[SPM2015] Diagram 19.1 and Diagram 19.2 show a fish seeing a beetle at different position. Why does the difference in sighting occur by the fish between Diagram 19.1 and Diagram 19.2?

• The sighting in Diagram 19.2 is done at an angle to the normal

• The mass of fish in Diagram 19.1 is bigger

• The distance between the fish and the beetle in Diagram 19.1 is further

[SPM2016] Which diagram shows the correct light path when light propagates through two layers of air with different temperature?

• 
• 
• 
• 

[SPM2016] Diagram 13 shows a boy observing a fish in a pond. The fish appears to be closer to the surface of the water. Which reason is correct to explain this situation?

• The refractive index of air > the refractive

  index of water

• The speed of light in air > the speed of light in

  water

• The density of air > the density of water

• The frequency of light in air> the frequency of

  light in water
