Q: What is the order of the first bright fringe in a single-slit diffraction pattern?
Solution:
In single-slit diffraction, the central maximum corresponds to m = 0, which is the first bright fringe.
Steps: 5
Show Steps
Step 1: Understand that in single-slit diffraction, light passes through a narrow slit and spreads out.
Step 2: Recognize that the central bright spot is called the central maximum.
Step 3: Identify that the central maximum corresponds to the order number m = 0.
Step 4: Realize that the first bright fringe on either side of the central maximum is the first order fringe.
Step 5: Conclude that the order of the first bright fringe is m = 1.
