How a CCD chip works
Next to every photodiode, there is a small "Image holder" (charge holding region). When a picture is taken, the light that hits the photodiodes is turned into an electrical charge, which is stored in the image holder.

An example of light acting as both a particle and a wave is the digital camera---the lens refracts (bends and focusses) waves of light that hit a charge-coupled device (CCD). The photons kick electrons out of the silicon in the CCD.
A telescope is an optical instrument that gathers and focuses light into a camera, CCD, spectrograph, or an astronomer's eye. Two major types of telescopes dominate astronomy: reflectors and refractors.
