A 0.56-mm-wide slit is illuminated by light of wavelength 640 nm . |
Part A What is the width (in mm) of the central maximum on a screen 2.0 m behind the slit? Express your answer using two significant figures. |
Here,
for the width of the central maximum
central maximum = 2 * wavelength * screen distance/slit width
central maximum = 2 * 640 *10^-9 * 2/(0.56 *10^-3)
central maximum = 4.57 *10^-3 m
central maximum = 4.57 mm
the width of central maximum 4.57 mm
