Questions & Step-by-Step Solutions
In a diffraction pattern, the intensity of the central maximum is how many times that of the first minimum?
Step 1: Understand what a diffraction pattern is. It is a pattern created when waves, like light, spread out after passing through a small opening or around an obstacle.
Step 2: Identify the central maximum in the diffraction pattern. This is the brightest spot in the pattern.
Step 3: Recognize that the first minimum is the first dark spot next to the central maximum.
Step 4: Know that the intensity of the central maximum is very high, theoretically considered infinite.
Step 5: Understand that the intensity of the first minimum is zero because it is a dark spot.
Step 6: Compare the two intensities. Since the central maximum is infinite and the first minimum is zero, the ratio is infinite.
