What is the period of dim light before sunrise called?
Answer. Twilight is the name given to the period between dawn and sunrise, or between sunset and dusk, when light is still visible in the sky due to sunlight scattering off the atmosphere.
What cause the reddish tint of the sun in the late afternoon?
A process called scattering. When the sun is low in the sky, the light has passed through so much atmosphere that nearly all of the blue wavelengths of visible light, orange and red- the dominant colors of light we see at sunride and sunset.
Why does the sky change colors at sunset?
Because the atmosphere bends the light.
Why is sunrise and sunset abrupt on the surface of the moon?
Because the atmosphere on the moon is very thin. On earth, the light refracts back down to earth, extending the sunrise and sunset. On the moon, the light has nothing in the atmosphere to bounce off of.
Why is the sky blue at midday and red at sunset?
Blue sky is due to 'Rayleigh scattering', which is 'blue shift' of the light (a Doppler 'compression' effect) on interaction with the particles forming the ionosphere and atmosphere. Red shift it when the atmosphere is rotating away from the sun's light so the waves are red shifted (a Doppler 'dilation' or extension effect). The scientific basis of this is assumed and considered as well understood by most but in fact is not. For instance there is sometimes a 'green flash' as the sun sets. We do not know precisely what causes it.
Why is the sun orange in appearance?
It's more of a white colour in space, but scattering of the light within our atmosphere gives it more of a yellow colour, or orange when it is closer to sunrise or sunset (more atmosphere to penetrate at these angles)

Why do ocean waters appear blue and skies at sunset appear red?
due to scattering of light .........
What is the scattering of light caused by suspended particles?
tyndall effect
What is the scattering of light caused by small suspended particles.?
tyndall effect
Why do we see spectacular events in the sky like rainbows red sunset and blue sky?
These spectacular events in the sky are caused by the interaction of sunlight with particles and molecules in the Earth's atmosphere. Rainbows are formed when sunlight is refracted and reflected by water droplets in the air, creating a spectrum of colors. Red sunsets occur when the sun's light passes through more of the Earth's atmosphere, scattering shorter wavelengths of light and leaving behind the colors with longer wavelengths, like red and orange. Blue skies are a result of Rayleigh scattering, where shorter blue wavelengths of light are scattered more than other colors by gas molecules in the atmosphere.
What is it called when light reflects in all directions?
Scattering. Caused by the light falling on 'bumpy' surfaces.
Why does the moon appear to have color during an eclipse?
Sunlight that passes through the Earth's atmosphere gets filtered by a process officially known as Rayleigh scattering; that is why the sky is blue, and the sunset is red. If some of that red light from the sunset reaches the moon, then the moon will also take on a reddish color.
What order are the colors in a sunset?
The colors in a sunset typically transition from red and orange to pink, purple, and blue. This order is due to the scattering of sunlight by particles in the atmosphere, which causes shorter-wavelength colors like blue and purple to disperse first, leaving longer-wavelength colors like red and orange to dominate the sky.
What cause the reddish tint of the sun in the late afternoon?
A process called scattering. When the sun is low in the sky, the light has passed through so much atmosphere that nearly all of the blue wavelengths of visible light, orange and red- the dominant colors of light we see at sunride and sunset.
Why does the sun appear yellow while the light it gives off is neutral white?
Sunlight is effectively "white light", and the yellow color is produced by the scattering of light by the atmosphere. This is easily seen near sunrise and sunset, where the additional atmospheric distance and angle make the Sun appear red.
Why does the sky change colors at sunset?
Because the atmosphere bends the light.
