Which colour of light from VIBGYOR has minimum energy?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Red.
- In the VIBGYOR spectrum, red light has the minimum energy.
- This is because the energy of light is inversely proportional to its wavelength.
- Red light has the longest wavelength among the colors in the spectrum, which means it carries the least energy.
- In the electromagnetic spectrum, energy increases as the wavelength decreases.
- Therefore, violet light, having the shortest wavelength, has the highest energy, while red light, with its longer wavelength, has the lowest energy.
- Understanding the relationship between wavelength and energy is crucial in various fields like optics and physics.
