Question

What happens when a ray of light falls on a white surface?

Answer 1

it gets reflected, on a black surface, it gets absorbed!!!!!

Answer 2

It will depend on the frequency or frequencies of the light "ray".  Some photons pass through, some get absorbed and their energy is re-emmited.  

The reason you see white is because the material is emitting an equal number of photons accross the range of around 380 to 770 trillion hertz.

Answer 3

Ideally the light ray should be reflected entirely. But no object is Ideal White Object, so a part of the light will always be absorbed by the surface. This energy (absorbed light) will be converted to heat energy and the surface will get heated up.

Answer 4

White is a color that has the property of reflecting all of the colors

of visible light.(the visible spectrum).

if light were to strike a different color,say green, the green wavelength

of light would be reflected,while the red and blue,would be absorbed,

and converted to heat.
