What are the causes of moons phases to occur?
as the earth moves so does the moon and where the earth orbits the sun and the moon orbits earth as the earth moves around the sun the sun projects light and it hits the moon and we can see the light from the sun reflecting off the moon
What is an increase in the wavelength of light as a galaxy moves away from earth?
Red Shift
How would you describe the movement of the sun in thirty minutes?
The sun does not move. The earth orbits (moves around) the sun!
What causes the position of the sun in the sky and shadows to change?
When the light is thrown on an object, shadow takes place on the opposite direction of the light source. So as the light source moves, the shadow does the same. The sun "moves" because the earth is rotating and revolving around it.
Why are there new phases of the moon each night?
The phases of the moon are determined by how much of the moon we can see from earth. The amount of the moon we see is determined by how much of the suns light is reflected from it back to us. As the moon moves round the earth and the earth moves round the sun the amount of light that gets bounced back from moon changes because of its different possitions.
Is the sun out at night?
yes it is. but the earth moves away from the sun at night and it moves out of its light and into darkness.
Starting with light source describe the path the light must travel to reach your eye?
The light moves from the source in a straight line to an object and then moves into the back of your eye to your retina.

What Movie earth to echo?
What MOVES the Earth to echo is the light of the Suns rays directly into the moving of the ocean

Describe how a light ray travels as it moves through empty space?
when light rays mave from one medium to another such as from air to water
Eclipse why does it happen?
A solar eclipse is when the moon moves in front of the sun casting a shadow on earth. A lunar eclipse is when the earth moves in front of the sun so the moon gets no light

Why is it light in day time and dark in night time?
Because the earth moves away from the sun
Where light comes from?

Light from a star travels from earth in a straight line at a constant speed of 300000 kilometers per second What is the acceleration of the light?
The speed of light is a constant, so the acceleration is zero. However, light IS affected by gravity, and gravity causes an acceleration. How does this balance? The light moves at the same speed - the speed of light, abbreviated "c" - but loses or gains energy as the light moves toward or away from the gravity source. In gaining energy (without speeding up!) the frequency of the light is increased and the wavelength of the light (or any electromagnetic energy) is decreased, In losing energy, the wavelength is increased and the wavelength decreased. This could be a trick question, of course. Light from a star wouldn't be travelling from earth, unless we are talking about reflected light, which would not be particularly intense, but it is not out of the question.
