What do most telescopes collect and focus?
All telescopes collect and focus light. Some concentrate on visible light while others look for infra-red, radio and microwave radiation.
What type of telescope has the simplest light path?
prime focus reflector
How do you improve the quality of image under light microscope?
by focus and magnification
What is the telescope that uses lenses to bring visible light to a focus?
refractor
What is the function of the codenser lens in the compound light microscope?
The function of a condenser lens is to focus the light onto a specimen. Condenser lenses are most useful at the highest powers of 400 x and above. Microscopes with a condenser lens render a sharper image than those with no lens. These lenses are able to move up and down.

They mirror they used to collect the light with was very slightly the wrong shape so the images were slightly out of focus.. Additional optical equipment was made to correct this. Effectively giving the Hubble 'spectacles'.
Why don't concave lenses being light rays into focus?
Simply put, light rays do not focus light because the focus is on the wrong side of the lens, with respect to the incoming light. If you draw the ray diagram you will see that the parallel rays transmitted may appear to be coming from a focus. This is what they mean by virtual.
How concave mirrors are employed to use light energy more effectively?
A concave mirror converges light rays falling on it. Parallel beams are converged to a point known as 'focus' of the concave mirror. In this way, most of the light rays falling on it are not deviated or lost. This helps in effective and optimum use of light where needed as in vehicle headlight, torch etc.
Where does the light focus on the retina?
