Explanation:

Scattering of light:
Scattering of light refers to the process in which light is deflected or scattered in various directions when it interacts with particles or objects in its path. This phenomenon explains several natural phenomena and colors we observe in our surroundings.

Red color of danger signals:
The red color of danger signals is a result of the scattering of light. When sunlight passes through the Earth's atmosphere, it undergoes scattering due to the presence of air molecules and other particles. The scattering of shorter wavelength colors like blue and green is more prominent, while longer wavelength colors like red are scattered less. As a result, the scattered light appears to be predominantly red, which is why danger signals are usually red in color.

Blue color of the clear sky:
The blue color of the clear sky is also a result of the scattering of light. The Earth's atmosphere contains tiny molecules, such as nitrogen and oxygen, that scatter short wavelength light more efficiently than long wavelength light. When sunlight passes through the atmosphere, the shorter wavelength colors like blue and violet are scattered in all directions. This scattered light is what we perceive as the blue color of the sky.

White color of clouds:
Clouds appear white because of the scattering of light by water droplets or ice crystals present in them. When sunlight passes through the clouds, the water droplets or ice crystals scatter all wavelengths of light equally. As a result, the scattered light appears white.

Advanced sunrise:
The phenomenon of advanced sunrise is not directly related to the scattering of light. An advanced sunrise occurs when the sun appears to rise earlier than its actual position due to atmospheric refraction. Atmospheric refraction is the bending of light as it passes through the Earth's atmosphere. This bending causes the sun to appear higher in the sky than it actually is, resulting in an advanced sunrise.

In conclusion, the scattering of light explains the red color of danger signals, the blue color of the clear sky, and the white color of clouds. However, the advanced sunrise is not directly related to the scattering of light.
