why cars or bikes have the yellow light explain by giving an appropriate reason.....

Answer:
Explanation:
It is crucial that fog lights are one color and one color only (rather than a usual headlight color of white, which is a bunch of colors). The reason is different wavelengths of colors hit droplets of fog differently.
This is dispersion, simply because the various shades within a color of light will leave one another, causing the image the light is hitting to disperse.
If you light up a foggy road with a light of just one color, the images you see in front of you will be a bit blurry because of the light hitting the fog, but this is much better than dispersion getting in your way using a color like white. Colors that have shorter wavelengths have the ability to scatter more light than colors with long wavelengths.
Our eyes are very sensitive to both yellow and green lights, so a yellow light has been chosen for people driving on the road in foggy conditions; yellow lights allow you to see the best distance in front of you during fog and it hits the fog in the best way.
Yellow light bulbs used in fog also give you the highest amount of illumination while using the least electricity. This saves you money on gas, and it also extends the lifespan of the bulbs.
Many people may wonder why the color yellow was chosen over red, as red really pops in a variety of parts of the car for visibility. The main reason is that red has already been chosen for brake lights.
In heavy fog, if another vehicle sees red lights they automatically will think it is break lights, and this can cause great confusion and can lead to accidents. Yellow lights are strictly used for fog situations, and for construction, so you can tell what is what on the road.
Yellow lights are also known to have sharper contrast at night and allow more focus for the driver. This increases the safety around the car in a heavy fog.
Another theory that is increasingly popular is that yellow light actually decreases stress during stressful situations. Whether you are driving in snowy conditions or intense fog, yellow light is calming and does not add to driver fatigue if you’ve been driving for a long time.
This is especially true during darker winter months where you might have a lot of fog in front of you. Yellow is easy on the eyes, and also creates defining outlines of obstacles that may come in front of you in fog.
