What lens function controls the amount of light that will exit the lens and expose the sensor?
SHUTTER in Camera controls the amount and time of light that the Sensor will exposed to.
If you break the lens on a camera what would happen?
There is an electronic light sensor in a camera; this sensor has what is called a "shutter" in front of it. When the shutter opens, the lens is responsible for focusing the outer light onto the sensor. Now if the lens is broken it will not be focusing the light, so the picture will be fuzzy beyond recognizing. I think it is worthy to mention that there are no lens cameras. They have a pinhole (or just a very small hole) which because of its smallness focuses the light.
What does a camera lens do?
Centers and refocuses light onto the camera's sensor.
What do camera lens do?

What part of camera lens lets light through?
The iris (technically the diaphragm) lets light from the lens enter the camera. The entire lens can let light fall on the film or sensor. But, much of the time it doesn't do that. An device called an iris makes the hole through which light passes larger and smaller. When all the way open it lets light from the entire lens reach the film or sensor, but it can make the hole smaller and only allow light from a part of the lens enter.
What does the lens on a digital camera do?
It focuses the light entering the camera onto the sensor.
What does the Len's do in a camera?
The lens of the camera projects the image onto the film or sensor.
What structure changes its shape to focus light at the back of the eye?
The lens of the eye also called the crystalline lens.
How is light reflected absorbed diffracted and diffused through a camera?
Light is diffracted and diffused as it enters the lens. Because the lens is not perfectly clear, some light is reflected. As the light strikes the sensor, it is absorbed and converted into electronic information.
What purpose the sensor serve on a digital camera?
The sensor senses light and image to adjust the auto focus, shutter speed, and lens aperture.
How is image quality measured on digital cameras?
Simple question - tough answer.There is currently no single "industry standard" for measuring image quality.Some aspects to consider:Color Reproduction (lens & sensor)ISO Performance (sensor)Sensor Size & Resolution (sensor)Dynamic Range (sensor)Image Sharpness (lens)CA Performance / Correction (lens)Light Falloff / Vignetting (lens)...and othersDigital cameras are bending and capturing light and storing that as a bunch of "1"s (ones) and "0"s (zeros). The number and complexity of the variables is staggering when you get into the details.
The camera is focused by?
The lens redirects light onto the sensor until the camera thinks it's in focus.
