What determines the color of an object give examples?

What determines the color of an object give examples?

The wavelengths that are reflected determine the color that an object appears to the human eye. For example, the leaves appear green because they reflect green light and absorb light of other wavelengths. Therefore, the wavelength of the transmitted light determines the color that the object appears.

What does it mean if an object appears blue?

When light hits a surface, some of it is absorbed and some of it is reflected. The light that is reflected is the colour of the object in that light. For example, a blue object absorbs all the colours of the spectrum except blue: it reflects blue light.

Why does a red ball appear red?

The Explanation This “red” ball contains colorants that absorb all of the colors of light, except red. The red light bounces off of the ball, and back into our eyes, causing us to perceive the ball as red. That means the ball is actually all of the other colors present in the light source, EXCEPT red.

Why are some colors absorbed and others reflected?

When atoms or compounds absorb light of the proper frequency, their electrons are excited to higher energy levels. Colored compounds absorb visible (colored) light and this absorption is responsible for their color. Our eyes perceive a mixture of all of the colors, as in the proportions in sunlight, as white light.

What color is an object if it reflects blue?

When white light falls on a blue surface, it reflects only blue and absorbs all other wavelengths. In fact blue is also first absorbed and then re emitted.

Why does an object look red in white light?

In most cases not all the light is absorbed by the surface and the light that is not absorbed is scattered. A red object is red when white light falls upon it because it absorbs all the components of white light with the exception of the red component which is scattered.

What colour is a red object in blue light?

A red object appears black under blue light. A blue object appears blue under blue light. A green object appears black under blue light. A red object appears black under green light.

Why do objects glow red when they absorb light?

Surfaces that are good at emitting certain frequencies of light are also good at absorbing the same frequencies. So if an object glows say red when energy is supplied to it, that means it is also good at absorbing red light. If you see it just in reflected light, the red will tend to be absorbed and missing from what you see.

Why do objects have different colors?

That’s why most of the objects we see in a well-lit environment have color. They are made of different materials and have different energy levels of the molecules, again. Though they can’t emit anything in the visible range, sometimes they can absorb visible light from the spectrum.

Why are most stars red in color?

Smaller stars are always red. Massive stars are blue. All stars can become giants, but only the massive blue ones can become giant blue ones. Since very few stars start out blue to begin with (less than 1% are massive enough), very few stars will become blue giants, and therefore most of the giant stars we see are red.

Why does a red ball appear red in the dark?

Though they can’t emit anything in the visible range, sometimes they can absorb visible light from the spectrum. For example, a bright red ball absorbs most of the visible colors, but reflects red back to your eyes. That’s why under white light you see it as red. You will not see it in the dark because it doesn’t emit any light.
