For an object to appear green, what must the object do to green light waves? O A. Shift them. O B. Reflect them. O C. Bend them. O D. Absorb them.
Solution
ANS: B) REFLECT THEM
This is because objects absorb most of the light, and reflect back the colour they are. So a yellow object under white light will absorb most of the colours of light, and reflect back the yellow light, so we can see yellow.
Because yellow light is a mixture of red and green light, yellow will also reflect red and green light. This means that a yellow object will appear red under red light, and green under green light. Yellow does not contain blue, so it will appear black under blue light.
