Why do we see a red apple as red?

• It emits red light

• It absorbs red light and reflects all others

• It absorbs all colors except red, which is reflected

• It changes the frequency of light waves

A beam of white light passes through a prism and separates into different colors. What causes this separation?

• Different wavelengths of light travel at different speeds in the prism

• The prism absorbs all colors except red and blue

• The prism creates new wavelengths through interference

• The white light is reflected instead of refracted

• b) White objects absorb more energy than black objects.

• c) Black objects absorb more wavelengths of light and convert them into heat.

• d) Light slows down when it hits a black surface.

A blue shirt appears blue because: a) It absorbs all colors of light and reflects only blue. b) It absorbs blue light and reflects all other colors. c) It reflects blue and green while absorbing red and yellow. d) The shirt changes the color of the light it absorbs.
