What happens to light when it is shone on a white object?

Colors of objects White objects look white because they reflect back all the visible wavelengths of light that shine on them – so the light still looks white to us. Colored objects, on the other hand, reflect back only some of the wavelengths; the rest they absorb.

Do objects look the same color when seen in white light or colored light?

A white object reflects all colors of white light equally. If an object absorbs all colors but one, we see the color it does not absorb. The yellow strip in the following figure absorbs red, orange, green, blue, indigo and violet light. It reflects yellow light and we see it as yellow.

What color shows up on white?

On a white, any dark color will do, and it’s more a matter of whether you want to convey urgency (red) or calm and stability (green and blue), or go with the matter-of-factness of black.

Can light change the color of objects?

Understand how the colours of objects change depending on the light they are viewed under. Turn out the room lights. So if a red light hits it it will appear red, but if a blue light hits it it will appear dark because it absorbs the blue light and reflects no light.

Why does a white object appear white?

Objects appear different colours because they absorb some colours (wavelengths) and reflected or transmit other colours. The colours we see are the wavelengths that are reflected or transmitted. White objects appear white because they reflect all colours. Black objects absorb all colours so no light is reflected.

Why does white light split into different colours?

White light can be split up to form a spectrum using a prism. The shorter the wavelength of the light, the more it is refracted. As a result, red light is refracted the least and violet light is refracted the most – causing the coloured light to spread out to form a spectrum. This is called dispersion .

Why do different colours of white light?

White light consists of seven colors with different wavelengths. The angle of deviation is inversely proportional to the wavelength of incident light. When white light hits the glass surface of the prism, the seven colors refract differently and get separated creating a spectrum.

What happens if you shine Coloured light on objects?

When we look at an object and see its color, we are seeing all of the light that reflects off of that object. Red objects reflect red light, green objects reflect green light, and so on. But what happens to the rest of the colors that hit that object? They get absorbed!
