Choose the correct statement.
- AWavelength of red light is less than violet light
- BWavelength of red light is more than violet light
- CWavelength of violet light is more than green light
- DWavelength of violet light is more than yellow light
- ENone of the above/More than one of the above
Show answer and explanation
Correct answer: (b) Wavelength of red light is more than violet light
Explanation
In the visible spectrum (VIBGYOR), red light has the longest wavelength (about 700 nm) and violet the shortest (about 400 nm).
So the wavelength of red light is more than that of violet light. Violet's wavelength is less than green's and yellow's, which rules out (c) and (d).
