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.

I found this picture of the light rays and it is a good example of the Incident rays making the focal point!!
The light bends.
yes. if light didn't travel through air, then you wouldn't be able to see anything!
through nothing
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.
Visible light and x-rays are both forms of electromagnetic radiation, and do not require a medium to travel through.
When light travels through anything that is not a vacuum, it will usually slow down.
When you click the camera the shutter behind the lens of the camera opens briefly and lets in the light on to the film. I am no specialist and this is what I learnt in school.
no if an object is OPAQUE then light can't travel through it (unless it has a hole in it)
Light does travel through a vacuum.
it cant travel through light.
Light will not travel through an opaque sponge.
Ofcouce Yes
light can travel through a vacuum whereas sound cant
The moon is opaque. Light cannot travel through it.
Both light and sound can indeed travel through glass. These are substances in which light and sound often travel through.
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
Light can travel through undistorted
Light can travel through transparent and translucent glass.
