Question

Which colour has maximum vibration speed?

• A. Blue
• B. Purple
• C. Green
• D. Black

Hint:

Purple (or violet) light waves have the highest frequency and therefore the fastest vibration speed in the visible spectrum.

Answer 1

The Correct Option is B

Step 1: Understanding vibration speed in colour theory
In physics, colours are associated with light waves, which vary in frequency and wavelength.
Vibration speed is related to frequency — higher frequency means faster vibration.

Step 2: Order of colours by frequency (from low to high)
Red < Orange < Yellow < Green < Blue < Indigo < Violet (Purple)
So, Violet or Purple has the highest frequency (and therefore the highest vibration speed).

Step 3: Evaluating options
(A) Blue $\Rightarrow$ High frequency, but not the highest.
(B) Purple $\Rightarrow$ Correct. Violet (Purple) has the maximum frequency.
(C) Green $\Rightarrow$ Medium frequency, lower than blue and purple.
(D) Black $\Rightarrow$ Black is the absence of light, not a vibrating light wave.
\[ \boxed{\text{Correct Answer: (B) Purple}} \]
