Answer:
At the end, no light passes through.
Explanation:
First, when white light enters a blue filter, only blue light is allowed to pass through, and all the other components of light are absorbed. When blue light then reaches the yellow filter, it absorbs the blue light, because it is designed to allow only the yellow component of the light to pass through. White light consists of the seven rainbow colours: red, orange, yellow, green, blue, indigo and violet.
