Question
What would happen if the danger signal color were green?
- The color will not be visible from a large distance.
- The color will not be visible if there is rain.
- The color will not be visible if there is smog.
- All of the above
Hint:
Green color has shorter wavelength as compared to red.
The correct answer is: All of the above
When color of shorter wavelength is used it will get scattered easily by the dust particles, water droplets and other particles present in the atmosphere and would not be visible to the human eye from a distance.
