Highway guardrails have a red reflector at one end and a green reflector at the other end to indicate the direction of travel for drivers. Red reflects oncoming traffic, while green indicates the intended direction of travel, helping drivers stay oriented and navigate safely.

Which would be a better reflector wood or metal?

Metal would generally be a better reflector than wood because metal surfaces tend to have higher reflectivity for light. This means that metal is more efficient in reflecting light and directing it in a specific direction. Wood, on the other hand, is not as reflective and would absorb more light rather than reflecting it.


What the relation between VDU and light reflector?

VDU (Visual Display Unit) is a device used to display visual information like a computer monitor or television screen. A light reflector, on the other hand, is a surface that reflects light. In the context of VDUs, light reflectors can be used to reduce glare and improve the visibility of the screen by reflecting ambient light away from the viewer, thereby enhancing the display quality.


What happens when light shines on green paper?

When light shines on green paper, the paper absorbs most of the colors in the light spectrum but reflects green wavelengths back to our eyes. This is why we perceive the paper as green. The green color is determined by the pigment molecules in the paper that absorb all other colors except green.

How do you charge the battery on lunar colony island?

There is a solar panel on the lunar rover. Climb to the top right of the Vehicle Bay and press the switch that opens the roof. When the light hits the reflector, change the angle of the other reflector to send the beam into the other reflector, then on to the next one, so that the light falls on the solar panel of the rover.
