What colour light will be seen after cyan light is incident on a yellow and then a blue filter?
no light
the yellow filter allows only red and green through.
To determine the color of light seen after passing through various filters, we need to understand how light interacts with filters.
Filters work by absorbing certain colors of light and transmitting or allowing others to pass through. When white light is incident on a filter, it contains all the colors of the visible spectrum. As the light passes through the filter, certain colors are absorbed, while others are transmitted.
Cyan light, which is a combination of blue and green light, will contain these specific colors. When it is incident on a yellow filter, the yellow filter absorbs blue light and allows green and red light to pass through. This means that after passing through the yellow filter, the cyan light will be missing its blue component and only contain green light.
Next, the cyan light with only green light will pass through a blue filter. The blue filter absorbs all colors except blue light, allowing only blue light to pass through. Therefore, after passing through the blue filter, the cyan light (containing only green light) will be completely absorbed. So, no light will be seen or transmitted.
In summary, after cyan light is incident on a yellow and then a blue filter, no light will be seen or transmitted through the filters.
