Question

The seven coloured rays in sunlight are known by the acronym of ________.
1. VIBGAOR
2. VIBXLOR
3. VIBJYOR
4. VIBGYOR

Answer 1

Correct Answer - Option 4 : VIBGYOR

The correct answer is VIBGYOR.

• The colours of the spectrum of white light are violet, indigo, blue, green, yellow, orange and red (VIBGYOR).
  • The white light is a mixture of different colours.
  • Each colour is associated with the light of a particular wavelength.

• Blue light has shorter waves, with wavelengths between about 450 and 495 nanometers.
• Red light has longer waves, with wavelengths around 620 to 750 nm.
  • Red has the longest wavelength and violet has the shortest wavelength.
• Violet waves have the highest frequencies.

• When all the waves are seen together, they make white light.
• Ultraviolet (UV) light is radiation with a wavelength shorter than that of visible light, but longer than X-rays, in the range 10 nm to 400.
