Energy ∝1/(wave length)
The energy of any of the colour is inversely proportional to its wavelength. According the VIBGYOR violet, Indigo and blue have the minimum wavelength, thus they have maximum energy level. So according to the options given in the question, blue has the maximum energy while red had the minimum energy.

Explanation:
The energy of a light wave is directly proportional to its frequency. The higher the frequency, the higher the energy of the light wave.
Comparing the frequencies:
To determine which light has the highest energy among blue, green, red, and yellow light, we need to compare their frequencies.
- Blue light: Blue light has the highest frequency among the given options. It has a wavelength range of approximately 450-495 nanometers, corresponding to a frequency range of about 606-668 THz.
- Green light: Green light has a slightly lower frequency compared to blue light. It has a wavelength range of approximately 495-570 nanometers, corresponding to a frequency range of about 526-606 THz.
- Red light: Red light has a lower frequency than both blue and green light. It has a wavelength range of approximately 620-750 nanometers, corresponding to a frequency range of about 400-484 THz.
- Yellow light: Yellow light has the lowest frequency among the given options. It has a wavelength range of approximately 570-590 nanometers, corresponding to a frequency range of about 508-526 THz.
Determining the light with the highest energy:
Since energy is directly proportional to frequency, we can conclude that blue light has the highest energy among the given options because it has the highest frequency.
Therefore, option 'A' - Blue light has the highest energy.
