Question 8 (02 pts) 600 nm passed etermine the diffraction divergence angle of a light beam with wavelength λ, through a circular aperture with diameter D 0.06 mm in an opaque screen Cl Ox Question 9 (02 pts)

Answer 1

Diffraction by a circular aperture is similar to singe slit diffraction theta_0 = 1.22 lambda/D theta_0 = 1.22 times 600 times 10^-9/0.06 times 10^-3 = 1.22 times 600 times 10^-9/6 times 10^-5 theta_0 = 0.0122 rad
