Answer 1

Answer:

$\bigstar$ A white object reflects all colors of white light equally. If an object absorbs all colors but one, we see the color it does not absorb.

Answer:

Question

1) What do you mean by the statement that the colour of an object is white or black?

Answer

Black and white are not fundamental colours . If an object absorbs all colours then it looks bleak and if it reflects all the seven colours of the sunlight , it looks white . For example , if sunlight falls on an umbrella , it absorbs all the incident light and no light is reflected . so a black umbrella appears black . Again , if the rays of the sun fall on a white cloth , the cloth reflects all the incident colours and so white cloth appears white .
