Answer 1

The correct answer is Red.Key Points

The energy of light is inversely proportional to its wavelength.
Therefore, the light with the longest wavelength, i.e. red, has the least energy.
The colours of VIBGYOR are arranged in increasing order of their wavelengths.
Hence, violet has the highest energy and red has the least.
Green is the colour of light with a wavelength between yellow and blue.
It has more energy than yellow but less than blue.
Yellow is the colour of light with a wavelength between green and orange.
It has less energy than green but more than orange.

Additional Information

VIBGYOR stands for Violet, Indigo, Blue, Green, Yellow, Orange, and Red.
- These are the seven colours of the visible spectrum of light.
Violet has the shortest wavelength and the highest energy among the colours of VIBGYOR.
Indigo is a colour that lies between blue and violet in the spectrum.
- It is not always distinguishable from blue and is not considered a separate colour by some people.
Orange is a colour that lies between yellow and red in the spectrum.
- It has more energy than red but less than yellow.
