Question: If the slit width is equal to the wavelength of light used, what is the expected diffraction pattern?

Options:

Correct Answer: Wide central maximum

Solution:

When the slit width is equal to the wavelength, a wide central maximum is observed due to significant diffraction.

If the slit width is equal to the wavelength of light used, what is the expected diffraction pattern?

If the slit width is equal to the wavelength of light used, what is the expected diffraction pattern?

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.

Diffraction – The bending of waves around obstacles and openings, which is significant when the size of the opening is comparable to the wavelength of the light.
Slit Width and Wavelength Relationship – When the slit width is equal to the wavelength, the diffraction effects are pronounced, leading to a distinct pattern.
Diffraction Pattern Characteristics – The resulting diffraction pattern will have a wide central maximum and diminishing side maxima due to the interference of waves.
