Want this question answered?
the part the red light touches will turn red...like if u get a red laser pointer and point it at a white paper.
The answer has a lot to do with why you call it "red paper". Could that be becausethe paper absorbs light of any other color, and reflects the red light toward your eyes ?
We see red when red light reaches the retinas in our eyes. A non-luminous object that looks red is absorbing every color of light that hits it except red light, which it reflects.
A purely green apple would look black under purely red light. If the apple were not purely green, it would look dark red. If the light were not purely red, the apple would look dark green. This is because red light does not reflect off purely green objects, and it is the reflected light which we see.
Since the apple is green, it would absorb any light that is not the same color as the apple. In this instance, the apple would appear very dark or even black since there is no green in the red light you are shining on the apple. A popular science experiment involves a shoe box, a piece of colored plastic or glass, a few objects (such as the apple), and a flashlight. If a red apple is being used with a red filter, the apple would appear to be a bright red since the apple is also red. The red filter allows the red color being reflected off the apple to pass through. Switch the filter to a green one, and the apple appears black since the filter effectively filters out all colors except green.
Because the skin of the apple absorbs all wavelengths of visible light EXCEPT red,so the red is the only one left to bounce off of the apple toward your eye.If there's no red wavelengths in the light that hits the apple, then it absorbs ALL ofthe light hitting it, and it appears black to you.

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. This is wrong an apple looks red to us because it reflects infrared waves.
All but red.
Yes
We see colour because light is made up different wavelengths. Objects absorb certain wavelengths of light while reflecting others. An apple appears to be red because it reflects the red wavelength while absorbing all the other colours.
We see colour because the normal white light is made up different wavelengths. Objects absorb certain wavelengths of light while reflecting others. An apple, reflects the red wavelength while absorbing all the other colours and so it appears colour red. If you pass sunlight through a prism in order to generate a spectrum, and hold the apple in each of the dominating colours, you will notice the colour of the apple changing.
the light becomes red :-P
