What causes us to see the moon is the Sun. The moon is usually above or below the Earth. So light from the Sun hits the moon and the moon reflects the light back. Some of it to Earth. For example, when a new moon happens the moon is in between the Sun and the Earth

SUN LIGHT> MOON EARTH

What happens there is that none of the light gets reflected off the part of the moon that we can see from the ground, giving the illusion that it is not there.

During a full moon the Earth is in between the Sun and moon

SUN LIGHT> EARTH MOON

Now, nearly all the light from the Sun gets reflected off the surface of the moon and to us on Earth

Answer from: Quest

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.
