- 1) Since very few students answered this problem correctly on the last exam, this is a chance for a re-do: The front of an abstract painting is showWn to the right. Nothing is drawn on the back-side of the painting. A person stands behind the painting and looks at the image of the front side of the painting reflecting from two sections of plane mirrors with reflecting surface (RS) at 90 degrees to each other. (She only sees the front of the painting in its reflection from the mirrors.) 2022 Use correct Ray Tracing techniques to describe how the reflected front of the painting appears to her. RS Front of painting 270° front of paintingYou are looking through the wall of the aquarium to a fish. Is the fish on the same distance as you see it, further or closer? Make a drawing.1. A ray of light is passing through air (n=1). It strikes a level surface of water (n=1.33) at an angle of 40° with respect to the surface of the water. The water is 10 cm thick. The light ray refracts and travels through the water. There is a level layer of clear polystyrene (n = 1.6) that the water is resting upon. The light ray hits the polystyrene level and travels through it, finally reaching a sheet of glass (n=1.45). Given that the speed of light in a vacuum is 3 x 108 m/s, calculate the speed of light in the water and the time it takes for the light to traverse the water layer. (actual question i need answered) *Using the arrangement in Problem 1, calculate the critical angle for total internal reflection at the polystyrene-glass interface

- (a) Does your bathroom mirror show you older or younger than you actually are? (b) Compute an order-of-magnitude estimate for the age difference based on data you specify.22.) Mirrors are optical devices that permit the reflection of light. A mirror demonstrates the law of reflection as it forms the image of the object placed before it. How is image formation possible on mirrors? Image formation is possible by means of paraxial approximation that makes use of light rays that form small angles with respect to the principal axis. Image formation is related to Snell’s law that states that the ratio of sin θi to the sin θr is equal to the ratio of the n2 to the n1. Image formation is possible when a light is reflected away from the normal as it passes from a denser medium to a less optically dense medium. Image formation can be traced using ray diagrams to identify the location, size, and nature of the image produced by different types of mirrors.
