You sight along the rim of a glass with vertical sides so that the top rim is lined up with the opposite edge of the bottom (Fig.a). The glass is a thin-walled, hollow cylinder 16.0 cm high. The diameter of the top and bottom of the glass is 8.0 cm. While you keep your eye in the same position, a friend fills the glass with a transparent liquid, and you then see a dime that is lying at the center of the bottom of the glass (Fig.b). What is the index of refraction of the liquid?

- The kitten, Simba (Fig. A) and the kitten, Bella (Fig. B) are inspecting a goldfish swimming inside a round aquarium filled with water (nwater = 1.33). The magnitude of the radius of the round surface of the aquarium is 16 cm. The kittens are in air (nair=1.00). In order to calculate the apparent depth of the fish as viewed by the kittens, you need to use the equation shown in Fig. C. Identify the following (Please note that I am not asking you to do the calculation) n₁ P Fig. A + n₂ 9 = (n₂-n₁) R Fig. C Fig. A: n₁ = Fig. B: n₁ = ; n₂ = _; n₂ = Fig. B ; R = ; R =Can you help me with the wrong. Please? Thank you.Suppose the two glass plates in Fig are two microscope slides 10.0 cm long. At one end they are in contact; at the other end they are separated by a piece of paper 0.0200 mm thick, have n = 1.52 and the spacebetween plates contains water (n = 1.33) instead of air. What happens now?
- A concave mirror has an object placed 20 cm in front of it. An image is formed 35 cm in front of the mirror. What is the magnification of the image?A convex lens has a radius of curvature of 20 cm. A 36-cm high object is placed 15 cm in front of the lens. Determine the location, nature, size, and orientation of the formed image.One end of the strip of a plane mirror is fixed and the other end rests on the top of the small vertical rod. The length of the plane mirror strip is 25cm. A ray of light is incident on the mirror and reflected from the mirror and forms a spot on a screen 3m away from the mirror. Now, if the top of the rod is moved upwards 0.1 mm, then what will be movement of the spot? A 0.24 cm B 3.4 cm 5 cm 4.5 cm
- A glass tumbler having inner depth of 17.5 cm is kept on a table. A student starts pouring water (μ 4/3) into it while looking at the surface of water from the above. When he feels that the = tumbler is half filled, he stops pouring water. Up to what height, the tumbler is actually filled ?A concave mirror has a focal length of 20 cm. What is the position (in cm) of the resulting image if the image is inverted and 2.9 times smaller than the object?Consider a mirror lying along the x-axis in R2. A laser starts at the point (−2, 6) and is fired in the direction of ⟨4, −3⟩. The beam travels until it hits the mirror, where it reflects off the mirror and then travels until it hits a wall on the line x = 20. (a) Give a parametrization for the initial path of the laser. (b) At what point does this beam hit the mirror? (c) Give a parametrization for the path of the reflected beam. (d) At what point does this beam hit the wall?
