What light can pass through a yellow filter?
A filter will absorb its complementary color of light. So a yellow filter absorbs blue light since blue is across from it on the color wheel. Whatever light is not absorbed will be transmitted; so yellow filters transmit red and green light (if incident upon it), also known as yellow light.
What color will objects appear if they are viewed through a green filter?

What colour light does a yellow filter transmit?
A yellow color filter will let through only yellow and absorb all other colors. 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 happens when yellow light passes through a green filter?
A filter will absorb its complementary color of light. So a yellow filter absorbs blue light since blue is across from it on the color wheel. Whatever light is not absorbed will be transmitted; so yellow filters transmit red and green light (if incident upon it), also known as yellow light.
How does a filter produce Coloured light?
When white light passes through a coloured filter, all colours are absorbed except for the colour of the filter. For example, an orange filter transmits orange light but absorbs all the other colours. If white light is shone on an orange filter, only the orange wavelengths will be observed by the human eye.
What colour filter will block red and green light?
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.
How is color seen through a colored filter?
Color filters absorb certain wavelengths of color and transmit the other wavelengths allowing them to be seen. We know that light is the source of color. For example, a blue flower absorbs all other colour wavelengths of light except blue, which it reflects making us see blue.
Why do we see a rainbow?
When sunlight hits a rain droplet, some of the light is reflected. The electromagnetic spectrum is made of light with many different wavelengths, and each is reflected at a different angle. Thus, spectrum is separated, producing a rainbow.
What would you see if you looked at white light through a yellow 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. This is why the object appears red. … A yellow color filter will let through only yellow and absorb all other colors.
Which statement best explains why an object appears green in the sunlight?

What color is seen when an object absorbs all the colors?
As shown in the next figure, an object is seen as black if it absorbs all colors of white 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.
