Question

0.800 m from a screen. light from the two slits al all W U II 35.20 – Two slits spaced 0.0720 mm apart are 0.800 m from a Coherent light of wavelength 1 passes through the two slits. In their interf ence pattern on the screen, the distance from the center of the central maxi mum to the first minimum is 3.00 mm. If the intensity at the peak of the central maximum is 0.0600 W/m², what is the intensity at points on the screen that are (a) 2.00 mm and (b) 1.50 mm from the center of the central maximum? 26.21 Consider tun antennas senarated by 9.00 m that radiate in
