Question

Amount of scattering is proportional to:
($\lambda :$ Wavelength, c: speed of light)

• A. ${\lambda }^4$
• B. ${\lambda }^{-4}$
• C. $c{f}^4$
• D. $c{f}^{-4}$

Answer 1

The correct option is B ${\lambda }^{-4}$

Amount of scattering is a function of wavelength of light. It is inversely proportional to the fourth power of wavelength of incident light.

$I\propto {\lambda }^{-4}$
