The light or image is focused at a different position relative to the real position of the emitting light. This is dependent on the type of lens.
Refraction
refracting
1 light hour like how a light year is how far light travels in a year.
A reflecting telescope.
Yes, light gathering power is proportional to the area of the objective. The more light a telescope can gather, the better the telescope will be able to allow the user to see.

Refraction
Red travels fastest Violet slowest.
It is refracted
by transmission , transmission is when the passing of light or other form of energy through matter .
it travels at c (speed of light in a vacuum)
When light travels through anything that is not a vacuum, it will usually slow down.
Light speed slows down in the glass.
the light goes through it and travels with each other.
what is the material through which light travels
The light is refracted (bent) causing it to separate into different colors.
