Why does the color of the light matter ?
notsponge [240]

Answer:

Recognizing the colors and identifying the color names is an important part of a child's development.Early identification of colors helps to create the cognitive link between visual clues and words.

Explanation:

Objects appear different colours because they absorb some colours (wavelengths) and reflected or transmit other colours. The colours we see are the wavelengths that are reflected or transmitted.White objects appear white because they reflect all colours. Black objects absorb all colours so no light is reflected.~Hope this helps!
