Could i please get some help with this, it would mean a lot, thank you !!!

Question 1 A single slit diffraction pattern is observed on a screen that is 1.10 m from the slit. The slit width is 195 times the incoming wavelength. How wide is the central maximum? C3 0.00282 m C.) 0.0113 m C 355 m C 107 m Question 2 \"man my 5 /L - 1 \"wet Him: 4.) At what angle does the laser beam need to be at to hit the mirror then hit the midpoint of the wall? The height of the room is h = 3.10m and the width of the room is w: 4.80 m. C) 0.770 rad C) 0.573 rad O 0.997 rad O 1.16 rad Question 3 An object is 43.0 cm from a converging lens and the object is 2.50 cm tall. What is the poisition and height of the image if the focal length ofthe lens is 23.0 cm? f\\ 'u The object is at 49.4 cm and the height of the image will be 2.87 cm inverted. O The object is at 0.0202 cm and the height of the image will be 0.00117 cm inverted. O The object is at 49.4 cm and the height of the image will be 0.00117 cm upright. , I \\ e/ The object is at 0.0202 cm and the height of the image will be 2.87 cm upright. 9. (Knight Problem 34.11) A 1.0-cm-thick layer of water stands on a horizontal slab of glass. A light ray in the air is inci- dent on the water 60' from the normal. What is the ray's direction of travel in the glass? [Answer: 350.] 10. (Knight Problem 34.31) A 1.0-cm-tall candle flame is 60 cm from a lens with a focal length of 20 cm. What are the image distance and the height of the flame's image? [Answer: 30 cm, 0.50 cm.] 11. (Knight Problem 34.33) A 2.0-cm-tall object is 40 cm in front of a converging lens that has a 20 cm focal length. a. Use ray tracing to find the position and height of the im- age. To do this accurately, use a ruler or paper with a grid. Determine the image distance and image height by making measurements on your diagram. b. Calculate the image position and height. Compare with your ray-tracing answers in part a. Answer: 40 cm, 2.0 cm.]
