### Find the width of the slit

Assignment Help Physics
##### Reference no: EM13251581

A laser beam passes through a single slit. We observe an interference pattern on a screen 9.03 m away. We find that the distance between the two dark lines (m = 1) on the two sides of the bright central maximum is 3.0 cm. The wavelength of the laser light is 633 nm. Find the width of the slit.
