If you hit your head on the roof while going through a yellow light, it probably means you were speeding through the intersection to avoid running a red.
The reason the filter appears yellow and is called a "yellow filter" is that only yellow light survives the trip through the filter and lives to emerge from the other side. If you don't hit it with yellow light, nothing comes out. If the light hitting the filter is pure blue and nothing else, you'll see no light come out, i.e. black.
When white light passes through a yellow filter, only the yellow wavelengths of light are transmitted while all other wavelengths are absorbed. This causes the light that passes through to appear yellow in color.
A yellow filter will allow yellow light to pass through easily. It will also transmit some red and green light, but will block out blue light.
When an object appears yellow, that means that most of the light bouncing off it is yellow light. If there is light of other colors hitting it, it's absorbing everything else except the yellow.
No, yellow paper does not absorb red light. Yellow paper absorbs blue light and reflects yellow light, giving it its yellow appearance. Red light is not absorbed by yellow paper, so it is reflected or transmitted through the paper.
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.
When a yellow light is passed through a green glass prism, the prism will refract the light, separating it into its component colors. In this case, the green glass will only allow green and yellow wavelengths to pass through, causing the yellow light to refract at a different angle than green light.
A yellow object absorbs blue light and reflects yellow light. This is because yellow is the combination of red and green light, which are not absorbed by the object.
When light shines on a yellow paper it passes through the paper and becomes yellow as the contrast of the paper is yellow hence the yellow color of the paper absorbs the light given and converts it into a yellow light.
A flashing yellow light means you should drive with caution when approaching and moving through the intersection.
black because blue light cannot pass through a yellow filter
The car making the turn must yield to the car going straight whether the light is green or yellow.
