How do you see black and white?
BlackAll of the colours that make the white light shine down on the black object and all of the colours that make the white light the light absorbs into the object and no light reflects.WhiteAll of the colours that make the white light shine down on the white object and the light and no light is absorbed into the object but all of the colours that make the white light are reflected into your eyes
How do colored filters absorb and transmit different colors of light?
Colored filters work by selectively absorbing certain wavelengths of light while allowing other wavelengths to pass through. The colors we see are the result of the reflected or transmitted light that is not absorbed by the filter. For example, a red filter absorbs most colors of light except for red, which is transmitted through the filter.
Why is it that no light reached the screen when a boy used white light from a spotlight and slotted a red filter and a green filter in front of it.?
When the boy used white light and placed a red filter in front of it, the filter absorbed all the colors of light except red, allowing only red light to pass through. Similarly, when he placed a green filter, it absorbed all colors except green. Since white light is a combination of all colors, the red and green filters absorbed all the light, hence no light reached the screen.
When White light passes through a yellow filter what colours are seen?
When white light passes through a yellow filter, only yellow light is transmitted, while all other colors are absorbed. This means that when you look at the light passing through the yellow filter, you will see only the color yellow.
What happens when light falls on a white objects?
We see colours because of white light (visible light) which is made up of red, orange, yellow, green, blue, purple light. We see colours when some fo these colours are absorbed into the object and the others are reflected. If an object is white that means all the light reflects off the object

What must happen to all wave lengths of light for a substance to appear white?
The colours we see in an object are only the colours that are reflected. Inferentially, the other colours are absorbed. The grass is green (when illuminated by a white light source) because the redder end of the spectrum is absorbed and used by the plant to do its stuff - photosynthesis and so on. A white card appears white because all the light wavelengths [to which we can respond] are reflected. That card may absorb some of the white light, but not at wavelengths to which we respond.

How can you filter light to create different colors?
Shining a white light through a glass prism will split the light into rainbow colours.

Which colors are absorbed by a white shirt?
No colour is absorbed and all the colours get reflected. Hence it looks white. But in case of black all colours get absorbed and so it looks black.
How can you change the color of white light?
White light is made up of all the colours in the spectrum. This can be proved by passing a ray of white light through a prism. As the light passes through the prism it will be split into the colours of the rainbow. Making a rainbow is one way of changing the colour of white lite. Another way is to filter the light - if you shine white light through a red filter then only the red bit of the white light will pass through, turning the light beam into a red beam.
When a white lite strikes a green object only the green component is absorbed?
A green object appears green because it reflects green light and absorbs all other colors present in white light. When white light strikes the object, the green component is absorbed and the rest is reflected back to our eyes, creating the perception of green color.
What Think of the seven colours of the rainbow Now explain why a stop sign appears red and white printer paper appears white?
We see colours because of the light absorbed by the object in view. White paper absorbs all the colours of the rainbow - so only white is reflected. A red stop sigh absorbs all colours except for red & white.
What happens to white light as it passes through a mangenta filter?
All other components of the white light, except magenta, are absorbed by the dyes in the filter, and only the magenta light comes out the other side. That's why the filter appears magenta when you look at it, and that's why the manufacturer cleverly named it a "Magenta Filter".
