about 10 sec
Okay, you're talking about the delay when the light turns red for one direction and then turns green for another direction. My guess would be that it would be to ensure that the intersection is clear before another direction of travel is given the green.
The duration of The Red Green Show is 1260.0 seconds.
The duration of The Red-Light Sting is 1.67 hours.
Green light - Green, White light - Green, Red light - Black
Mixing red and green light produces yellow light. This is because red light and green light combined stimulate both the red and green cone cells in our eyes, creating the perception of yellow.
No, red light is lower frequency than green light.
The green light would be reflected, but the red light would be absorbed. ---Ryan Wang---

a green light
While the ball would still be green it will appear black. Anything green absorbed all colours except green. The green light is reflected to your eyes which makes it look green. Thus in red light (with no green in it) the red will be absorbed and no green light can be reflected to your eyes so the ball will look black.
