Final answer:
The exposure times that can be used with video-disc recorders are 100 milliseconds, 500 milliseconds, 5 milliseconds, and 10 milliseconds. The correct option is 5 milliseconds.
Step-by-step explanation:
When using video-disc recorders, exposure times can be reduced to:
1. 100 milliseconds
2. 500 milliseconds
3. 5 milliseconds
4. 10 milliseconds
The exposure time is the length of time the camera's shutter is open, allowing light to reach the camera's sensor. A faster shutter speed, indicated by a smaller number, can freeze action and reduce motion blur. In this case, the faster the shutter speed, the shorter the exposure time.
Therefore, the correct answer is option 3: 5 milliseconds.
