Alinearly polarized light with a wavelength of 600 nm illuminates a single slit having a slit width of 0.1 mm. estimate the distance of the third bright fringe from the center when a screen is located at a distance of 2 m from the slit. (8 marks) (b) a light beam is incident on a glass medium from air. when the incident angle matches the polarization angle, e, find the angles of the incident, refracted and reflected beams measured with respect to the normal. construct the corresponding plane of incidence for (1) s-polarized incident beam and (ii) p-polarized incident beam. the plane of incidence should include the angles of incidence, refraction and reflection, and the polarization states of the light beams. assume that the refractive indices are 1.5 and 1.0 for the glass and air, respectively. (10 marks) consider two light sources with a wavelength of 500 nm placed to the left of a convex thin lens having a focal length of 10 cm, as shown in figure 1 on page 3. given that their images are formed on a screen placed 11 cm away from the lens, determine the location of the light sources l measured with respect to the lens. if the images formed satisfy the "just resolved" condition, find the separation distance d between the two light sources. assume that the lens is 2 cm in diameter, and note that figure 1 is not drawn to scale
