V Part A A glass plate having parallel faces and a refractive index of 1.58 lies at the bottom of a liquid of refractive index 170. A ray of light in the liquid strikes the top of the glass at an angle of incidence of Compute the angle of refraction Of this light in the glass. 58.0o . Express tour answer in degrees. Iwo Muest Answer Part A A parallel-sided plate of glass having a refractive index of 1.59 is in contact with the surface of water in a tank. A ray coming from above makes an angle of incidence of 29.6 . with the normal to What angle does this ray make with the normal in the water? the top surface of the glass. Express your answer in degrees. IVO AEQ ? D = Submit Request AnswerHEFLECT The image is inverted (as we know because in = -30 is negative) and is 30 times taller than the object. Notice that the filament is not located at the In this example, we will find the position and magnification of an mirror's focal point; the image is not formed by rays parallel to the optic axis. (The focal length of this mirror is f = R/Z = 9.7 cm.) image formed by a spherical mirror. A lamp is placed 10 cm in front of a concave spherical mirror that forms an image of the filament on a screen placed 30 m from the mirror. What is the , radius of curvature of the mirror? What is the lateral v Part A ' Practice Problem: magnification? If the lamp filament is 5.0 mm high, how tall is its image? Aconcave mirror has a radius of curvature R = 21 cm, An object of height 5.0 cm is placed 15 cm in front of the mirror. What is the image distance? Express your answer with the appropriate units. 5' = Value Units -Mw V Part B - Practice Problem: Figure 1 of 1 What is the height of the image? Express your answer with the appropriate units
