Q
Q: For a single slit of width 'a', what is the angular position of the first minimum?
Solution:
The angular position of the first minimum is given by sin θ = λ/a.
Steps: 5
Show Steps
Step 1: Understand that we are dealing with a single slit of width 'a'.
Step 2: Know that when light passes through a slit, it creates a pattern of bright and dark spots on a screen.
Step 3: The dark spots (minima) occur at specific angles, which we can calculate.
Step 4: The formula for the angular position of the first minimum is given by sin θ = λ/a, where λ is the wavelength of the light.
Step 5: To find the angle θ, you can rearrange the formula to θ = arcsin(λ/a) if needed.
