Explanation:

Answer 2

Yellow light is more energetic than red light.

• The energy of light is directly proportional to its frequency as

        E = hν, where h is Planck's constant

• Also, ν = c/λ

             ⇒ ν = hc/λ

             ⇒ ν ∝ 1/λ

• So, we can see that the frequency of the light is inversely proportional to the wavelength.
• The wavelengths of the given light in increasing order is

        red > yellow > blue > indigo.

• So the increasing order of the energy of the light is indigo

        red < yellow < blue < indigo.

Hence, we can conclude that yellow light is more energetic than red light.
