A diaphram with round aperture, whose radius r can be varited during the experiment, is placed between a point source of light and a screen. The distance from the diaphram to the source and the screen are equal to a = 100 cm and b = 125 cm . determie the wavelength of light if the intensity maximum at the centre of the differaction pattern of the screen is observed at r_(1) = 1.00 mm and the next maximum at r_(2) = 1.29 mm .
