Q1:a) Parallel rays of green mercury light with a wavelength of 546 nm pass through a slit covering a lenswith a focal length of 60.0 cm. In the focal plane of the lens the distance from the central maximum to thefirst minimum is 10.2mm. What is the width of the slit?b) Unpolarized light of intensity 20 W /cm² is incident on two polarizing filters. The axis of the firstfilter is at an angle of 25.0° counterclockwise from the vertical and the axis of the second filter is at62.0°counterclockwise from the vertical. What is the intensity of the light after it has passed through thesecond polarizer?
