Question

Procedure: Fill the glass about 2/3 full of water. Take the pencil and immerse it vertically in the water. Move the pencil in a circular motion around the inside of the glass while viewing the motion from the side of the glass (as shown in the side view below and top view). Pencil I Water A Pencil side view top view Write your observations and answer questions for each of the following: 1. Briefly describe your observations of the pencil as it moves in a circle inside the glass. 2. Describe where in the circle the pencil in the water appears most like the pencil out of the water. 3. Describe where in the circle the pencil in the water appears most broken from the pencil in the air. (most separated) Rates) Focus

Answer 1

moves 1o As Even though pencil actually circular motion, it appears as if it is moving in Horizontal direction from the side view. ~ The enlargement and seperation of the pencil illusions are obersered At this point of circle pencils in water wehere appears out of the water.ie at the point the pencil is closest to you. > At this point of circle pencil in water appears most broken from the pencil in air. a That is at the points of farther left and right corners of the glass. At the point where pencil is outside the water along the length of pencil, it appears to be broken. At the right and left most corners the circle away of from you. CS Scanned with CamScanner

No It's not the same. In the olive oil case, magnified and separated. more it is much Because of high refractive index of oil. This time both magnification and separation both are increased. eod 10 ③ Yes, it appears appears now more broken than in the water becaused of the addition of layer of glass beyo and water glass layers before. It appears most broken at the corner or at the best extreme left and right positions This is also at to extreme left and right 10 corners. position reflected ☺ The x light rays coming from pencil bend in water as well as they pass through the وما و from - The when they pan light rays coming the part of the pencil which in air only bend through a glan. » The Cine of anis pencils is away from the anis when see, you the are the separation and Magnification CS Scanned with CamScanner

imam maxim minimum. - If the pencil is in the Axis of view, magnification and separation - Overall, Refraction of light is happenning This Hasion causes the illusion of pencil being broken and Magnified. CS Scanned with CamScanner
