Question

Question 8 You are conducting an experiment on the diffraction of light through a single narrow slit. You have situated your viewing screen a distance of 1 m away from the slit, with blue light of 450 nm and the slit width is 2.4um. You observe a normal interference pattern with a bright central maximum. What happens to the central maximum if you switch out the 2.4um single slit for a 4.8um single slit? No change occurs to the central maximum. The central maximum becomes narrower. The central maximum becomes wider. The central maximum would disappear completely Question 9 You have a fancy laser that emits two colors of light along the same beam path. The two colors of light are red and blue, and you decide to shine them through the lens used in the "Reflection & Refraction" lab to study refraction and Snel's Law. When the angle of incidence is 20° going from air to plastic, what would you expect to observe? Refraction20 D DE 02 Type of Light Incident Material Ext Material The blue light would be refracted, and the red light would be reflected The blue light would be reflected, and the red light would be refracted. The angle of refraction for the blue light would be slightly larger than the angle of refraction for the red light. The angle of refraction for the blue light would be slightly smaller than the angle of refraction for the red light. Both colors of light would be perfectly refracted together with no separation whatsoever according to Snell's Law
