Q
Q: If the slit width is equal to the wavelength of light used, what is the expected diffraction pattern?
Solution:
When the slit width is equal to the wavelength, a wide central maximum is observed due to significant diffraction.
Steps: 6
Show Steps
Step 1: Understand that diffraction occurs when light passes through a narrow opening (slit).
Step 2: Recognize that the slit width is equal to the wavelength of the light used.
Step 3: Realize that when the slit width is equal to the wavelength, the light spreads out more than usual.
Step 4: Identify that this spreading creates a pattern of light and dark areas on a screen.
Step 5: Note that the central area of light (called the central maximum) will be very wide and bright.
Step 6: Understand that there will be smaller, less bright areas (called minima) on either side of the central maximum.
