postman are leally allowed to go through a red light
In the UK, postmen are allowed to go through a red light if they are operating in the course of duty and it's safe to do so. This is under the 'crown exemption' which allows emergency vehicles and vehicles on important governmental business to bypass certain road regulations in specific circumstances.
It means you should stop and wait for a green light to go through the intersection.
No there is no special permission for a hearse to go through a red light, unless such a vehicle is accompanied by the police and permission has been given. Such instances would be for royal (state) funerals.
Meaning it's STOP not GO in one case... In the other, red lights are red because... The light passes through a red filter which colors the light red. It comes to our eyes as red, and we see it as red.
After pure, white light passes through a red filter, all the other colors in the spectrum will flow out of the other side. My mistake, I had a faulty source. A red light filter will cause the image to appear as different shades of red. Since it is a red filter only red light can pass through. So you finish up with red light. Whether it is focussed to an image or not is of no consequence. As to different shades of red, you will get the shade of red that is passed by the filter.
a cloud is sometimes red orange or pink because of the way the sunlight goes through the layers of atmosphere.The light also has to go through the cloud and go a long way to get to your eyes.
A colored filter absorbs certain wavelengths of light and only allows specific colors to pass through. The color of the filter determines which wavelengths are transmitted and which are absorbed. For example, a red filter absorbs blue and green light, allowing only red light to pass through.
No, using a red light with green and blue filters will not make white light. White light is a combination of all visible colors, so you would need to use all three primary colors (red, green, and blue) together to create white light.
As light moves through the atmosphere, it continues to go straight until it bumps into a bit of dust or gas molecules
