• A. Clouds don't scatter light
• B. Clouds scatter only blue light
• C. Clouds scatter all colors of light
• D. None of these

Answer 1

The correct option is C

Clouds scatter all colors of light

$\begin{array}{cc}\text{Statement}& \text{Options}\\ \text{(A)Light makes tiny particles visible due to}& \text{(1)Tyndall effect}\\ \text{scattering.}& \\ \text{(B)The effect of seeing an objects is retained by the}& \text{(2)Persistence of vision}\\ \text{eye for}\frac{1}{{16}^{th}}\text{of a second.}& \\ \text{(C)Composite light splits up into component}& \text{(3)Dispersion}\\ \text{colours.}& \\ \text{(D)Irregular and partial reflection of light}& \text{(4)Scattering}\end{array}$

Definition for the given terms:

Tyndal effect: It is the scattering of light as light beam passes through a colloid. The individual suspension particles scatter and reflect light, making the beam visible.

Persistence of vision: When an object is viewed by the eye, its image remains on the retina of the eye for a time interval of 0.0625 seconds ($\frac{1}{16}th$). If more than one object is viewed within 0.0625 s, their images will appear interrelated subsequently to the eye.

Dispersion: It is the phenomenon of splitting up of a composite light into its constituent colours. The regular array of colours formed by dispersion is the visible spectrum.

Scattering: it is the phenomenon of reflection and deflection of light from its linear path after passing through a non-uniform medium.
