A 'red' apple does not emit red light. Rather, it simply absorbs all the frequencies of visible light shining on it EXCEPT for a group of frequencies that is perceived as red, which are REFLECTED. An apple looks red to us because it REFLECTS infrared waves.

Answer:

Reflects the red light

Explanation:

The optical physics says that whatever color we perceive for any object is the color of the light of any particular wavelength that is reflected by the object instead of observing. Rest all form of light waves except the one which is reflected are absorbed or transmitted by the object. For instance – leaves appear green because they reflect the green light and this is the reason that when plants are exposed to green light they are not able to photosynthesize.
