Question

6. Three identical towels of red, blue and green color are hanging on a cloth line in the sun. What would be the color of shadows of these towels?

Answer 1

the colour of the shadow is always black no matter the colour of the object as when light is blocked shadow is formed and light brings colour essentially the colour formation is impossible due to light being blocked

Answer 2

The color of shadows of these towels are black bluish irrespective or whether the towel are red, blue or green color all will have shadows of black color.

Color of shadow is black bluish because light source is blocked by an opaque object.It occupies all three dimensional volume behind an object with light infront of it.

The shadow cast by an opaque object during daylight illuminated by sunlight has black bluish color due to Rayleigh scattering, the property that causes sky to appear blue.

The opaque object is able to block the light of the sun, but not the ambient light of sky which is blue as atmosphere molecules scatter blue light more effectively so as a result shadow is bluish.
