Listening to your stereo system while driving can be dangerous because: a. drivers may try to adjust it frequently b. it can make driving more monotonous c. music makes it harder to focus on the road

C. Music makes it harder to focus on the road.

Explanation:

The main reason why listening to your stereo system while driving can be dangerous is because music makes it harder to focus on the road. While driving, you need to be fully aware of everything that goes on around you. This includes sights and noises. If your attention is directed towards music, you are more likely to miss what is going on in the road.

scattering of light by tiny particles in air to produce the colors we see on sky, is dependent on the following factors:

(i) wavelength of light

(ii) size of the scattering particle  

(iii) distance traveled by light through the atmosphere.

according to rayleigh's law of scattering, the amount of scattering is inversely proportional to the fourth power of its wavelength. shorter the wavelength, greater is its scattering. hence violet/blue light is scattered more than red.

sun's light is a composite light ( visible light) with wavelengths in the range 400 nm (violet) to 700 nm (red). as sunlight passes through our atmosphere, the molecules of air scatter light according to their wavelengths. during sunrise and sunset, the sun's position is below the horizon. hence light from the sun travels a greater distance in the atmosphere when compared to its position a noon.

as sunlight enters the earth's atmosphere, blue light is scattered away and at the end of its journey in the sky, only red and orange wavelengths remain in the beam.

hence at sunrise and sunset, the sky appears reddish orange.
