Questions & Step-by-Step Solutions
In a single-slit diffraction pattern, the width of the central maximum is 4 mm. If the slit width is halved, what will be the new width of the central maximum?
Step 1: Understand that in a single-slit diffraction pattern, the width of the central maximum is related to the width of the slit.
Step 2: Know that if the slit width decreases, the width of the central maximum increases.
Step 3: The original width of the central maximum is given as 4 mm.
Step 4: If the slit width is halved, this means the slit is now narrower.
Step 5: Since the width of the central maximum is inversely proportional to the slit width, halving the slit width will double the width of the central maximum.
Step 6: Therefore, the new width of the central maximum will be 4 mm (original width) multiplied by 2, which equals 8 mm.
