Question

light appears white. why?​

Answer 1

Answer:

Objects appear different colours because they absorb some colours (wavelengths) and reflected or transmit other colours. ... White objects appear white because they reflect all colours. Black objects absorb all colours so no light is reflected.

Answer 2

Answer:

White light is a mixture of all colors, in roughly equal proportions. White objects look white because they reflect back all the visible wavelengths of light that shine on them - so the light still looks white to us. Colored objects, on the other hand, reflect back only some of the wavelengths; the rest they absorb.
