Light from a helium-neon laser wavelength633 nm is focused

Reference no: EM13631220

Light from a helium-neon laser (wavelength=633 nm) is focused through a pinhole prior to illuminating a 1.00 mm diameter aperture. If the pinhole is located 50.0 cm behind the diffracting aperture, how far in front of the aperture should an observing screen be located to give a Fresnel number of ten?
