Final answer:
The total brightness gain for an image intensification tube can be calculated using the formula: Total Brightness Gain = Minification Gain * Flux Gain. In this case, the minification gain is 25 and the flux gain is 50, resulting in a total brightness gain of 1250.
Step-by-step explanation:
The total brightness gain for an image intensification tube can be determined using the formula:
Total Brightness Gain = Minification Gain * Flux Gain
In this case, the minification gain is 25 and the flux gain is 50. Plugging these values into the formula, we get:
Total Brightness Gain = 25 * 50 = 1250
Therefore, the correct answer is D) 1250.
