Question

Let us have three colors – red, green and blue of VIBGYOR. Which of the following arrangements shows the correct order of highest scattering ability to least scattering ability?

• A. Red > Blue > Green
• B. Blue > Green > Red
• C. Green > Blue > Red
• D. Blue > Red > Green

Answer 1

The correct option is B Blue > Green > Red

We know that:
$I\alpha \frac{1}{{\lambda }^4}$
I = Intensity $\lambda$ = wavelength
And In VIBGYOR Red has the largest wavelength Green has wavelength less than red And Blue is having the least wavelength among the given three So lesser the wavelength, higher the Intensity and higher will be the scattering nature. So we can say that The correct order will be: Blue > Green > Red
