Question

A person flying in a plane over Easter island notices that the water around the island appears bluer than the surrounding water. What property of light waves causes the water to be a different color to the observer?
1.Absorption
2.Diffraction
3.Reflection
4.Refraction

Answer 1

Answer: 3.Reflection

Explanation:

The color of the objects is due to the light reflected to our eyes.The light falls on the surface of the object and the color which does not get absorbed by the object gets transmitted and thus appear to be of the same color as the reflected light. If an object absorbs all of the frequencies of visible light except for the frequency associated with blue light, then the object will appear blue

Absorption is defined as the process when one thing becomes part of another thing.

Diffraction is the phenomenon in which light bends around the corner of the obstacle in its path.

Reflection is the process in which light bounces off the surface when it strikes the surface.

Refraction is the bending of light when it passes from one medium to another.

Answer 2

The correct answer is Reflection.

When the light falls on the island which basically has lots of water then the light rays gets reflected back. This reflected rays makes the water look more bluer than the surrounding water. The phenomenon of reflection made water look more blue. As the thickness of water increases it appears to be more bluer than the surrounding less thicker water.
