Chapter 14, Problem 2RAT

A rainbow illustrates the properties of

(a) reflection.

(b) refraction.

(c) dispersion.

(d) All of these.

Solution

To determine: The correct option for the statement “A rainbow illustrates the properties of”.

Answer:

The correct option for the statement “A rainbow illustrates the properties of” is option (d).

Explanation:

Reflection is the process in which a light-wave sends back after striking the surface of the object. Refraction is the process in which light-wave bends when it enters from one medium to another. Dispersion is the process when the light wave splits into the number of colors.

A rainbow is formed when the light-wave undergoes a single reflection, which occurs inside the water droplet and double refraction. The first refraction occurs between the atmosphere and water medium, and the second refraction between the water droplet and atmosphere, and then there is dispersion means splitting of the light occurs.

Conclusion:

Therefore, the correct option for the statement “A rainbow illustrates the properties of” is option (d).
