The Lens is the image-forming device on a camera. The lens bends light rays to project an image onto a light sensitive medium, which may be any of several forms, including film, sensitized glass plate, or electronic sensor.
The Diaphragm is a variable opening which controls the quantity (brightness) of light falling on the light sensitive medium.
The Shutter controls the length of time light is permitted to fall on the light sensitive medium. It can take many forms, but usually has some method for precision adjustment of the time it is open.
Light passing through the lens, aperture, and (when open) the shutter forms an image of specific brightness for a specific duration on the light sensitive medium.
Light also passes through a viewfinder system, which may be a part of the optical system of the camera, or separate from it. In the most complex cameras, some of the light passing through the lens is diverted into a viewfinder by means of a mirror or prism. By using some of the same light passing into the camera, these systems permit the user to see essentially what the camera is seeing.

What gathers light through a lens and project an image on film called?
The thing that gathers light through a lens and projects an image on a film is... its really rather simple. Its a camera. How easy was that! So to explain the process, A camera gathers and bends light with a lense, this lense then projects an image onto a light-sensitive film to record a scene. When you take a picture with a camera, a shutter opens to allow light to enter the camera for a specific length of time.
Do visible light and x-rays travel through different medians?

Can both light and sound travel through glass?
Both light and sound can indeed travel through glass. These are substances in which light and sound often travel through.
How does a physical filter transmit light to a camera?
The filter sits at the end of the lens. All light cannot enter the camera without first going through the lens. And light cannot enter the lens without going through the filter, so the light goes through the fliter, then through the lens, then into the camera
