What color is blocked by a blue filter?
For instance, a blue filter will block yellow light.
However, this question is written in terms of the primary colors of light.
So yellow light is actually a combination of the two primary colors red and green (refer to color wheel).
So a blue filter will block red and green light..
What colors absorb the most light?
the color strips. Obviously the black strip absorbed the most. But the red, blue, and green ones did not absorb much.
What color has lowest frequency?
redThe part of the EM spectrum that we are able to see begins with red (the lowest frequency of light) and ends with violet (the highest frequency of light). White light is the combination of all the colors of the spectrum (red, orange, yellow, green, blue, indigo, & violet).
What colors does Blue absorb and reflect?
A blue pigment is capable of absorbing yellow light. That is, blue paper can absorb both red and green primary colors of light (recall that yellow light is a mixture of red and green light). So red and green light shine on the paper; and both the red and the green light are subtracted.
Which Colour Has Highest intensity?
Waves with a short wavelength have the most energy. Red waves have a relatively long wavelength (in the 700 nm range), and violet waves are much shorter – roughly half that. Because violet waves have the shortest wavelength of the visible light spectrum, they carry the most energy.
Does a red filter block blue light?
A blue filter absorbs all light whose wavelength does not fall within the range of blue light; hence, all objects seen through a blue filter appear blue. A red filter works in the same way; only red light is allowed to pass through.
Why does Red absorb blue light?
Red is the lowest energy visible light and violet is the highest. … If it absorbs light in the red and yellow region of the spectrum, it will have a blue color. Here is an example. Chlorophyll, the pigment that makes plants green, absorbs light in the red end of the spectrum and light in the blue end of the spectrum.

What happens when white light passes through a blue filter?
When white light shines on a red object, all of the colors that form the white light are absorbed except red, which is reflected. … So when blue light is allowed through a blue filter onto a blue object, the object will still reflect blue and therefore appear blue.
What color will we see if an object is absorbing all of the colors of 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.
What color does a red filter allow through?
If you pass white light through a red filter, then red light comes out the other side. This is because the red filter only allows red light through. The other colours (wavelengths) of the spectrum are absorbed. Similarly, a green filter only allows green light through.
What happens when you shine a red light on blue paper?
So shining red light on a blue object would, in an ideal world, show it as black. In the real world no object is perfectly blue, it will reflect some light outside the blue.
