Question

I need help with part C, and part be is done but font know if its right, please help and thank you in advance. Show all work

B. Suppose that a pencil were held vertically at the back of a circular beaker of water, as shown. (The portion of the pencil below the surface of the water is not shown) Note: The center of Optics Interpretation of ray diagrams ADO 170 the beaker is marked by an "X." Pencil Is the image of the bottom of the pencil closer to farther from, or the same distance from the observer as the top of the pencil? Top of pencil Circular beaker of water Sketch a qualitatively correct ray diagram to support your answer The image of the pencil is the same distance as the top of the pencil. becouse of refrac Hon light path bends. Eye Cross-sectional top view Front view Use the method of parallax to place a second pencil at the location of the image of the bottom of the pencil, and check your predictions. If your prediction was incorrect, find your error. C. Three students are discussing their results from part B: Student 1: "think that the image is closer to me than the pencil itself. The closer something is the bigger it looks. Because the image of the pencil appears wider than the pencil itself, the image must be closer to me than the pencil." Student 2: "That sounds reasonable, but when I used parallax to determine the location of the image of the pencil, I found that it was farther from me than the pencil Student 3: "That doesn't make sense though. If the image were behind the pencil, then how could I see the image? Wouldn't the pencil block my view of the image Do you agree or disagree with each of these students? Discuss your reasoning with your partners. Tidorials in Introductory Physics McDermott, Shaffer, & P.E.G., U. Wash. Prentice Hall,

Answer 1

Part B is right and has been solved properly .

Part C

Student 1 : Seeing the image big doesnot mean that the object is closer to you in all senses .When the magnification happens image appears bigger without a change in position .As light traveks through the denser medium refraction takes place and hence the image of the pencil looks bigger than the pencil .Infact is doen't mean that the image is closer.

Student 2 : In the method of parallax we cannot take into consideration the refrcation happening when the light passes through glass , through water and then through glass again into air .So by the method of parallax we see the image to be farther than the pencil.

Student 3 : I agree that is right because then the image would not be viewed.We can actually see the image because the image is not formed behind the pencil and infact in front of it .

P.S.if this helped you please like the answer.Thankyou.
