6. A solid glass sphere with a radius of 5.00 cm and index of refraction of 1.52 has a small coin embedded 3.00 cm from the front surface of the sphere. For the viewer looking at the coin through the glass, at what distance from the front surface of the glass does the coin’s image appear to be located?
2. A sphere of glass with index of refraction n 1.7 and radius 5 cm has been cut, as shown below, to make a thin lens. The focal length of this lens is (the sign indicates converging or diverging, as usual, closest answer in cm) (a) -1.2 (b) 1.2 (c) -5.3 (d) 5.3 (e) -7.1 (f) 7.1
A glass cylinder of 2 cm radius and index of refraction 1.52 is surrounded by a cylindrical plastic shell of index of refraction 1.40. Light is emitted from a source within the glass cylinder. For what range of angles relative to the cylinder axis will the light not escape the glass? Answer is < 22.9 degrees but please show work and explain a) < 22.9 degrees b) > 22.9 degrees c) < 67.1 degrees d) > 67.1 degrees
1.) A double-concave lens focal length -20 cm has an object placed at a distance of 30 cm in front of it. How far from the mirror is the image formed? On what side of the lens is the image formed? What is the magnification? Is the image real or virtual? Upright or inverted? 2.) The second order fringe is located 5-cm from the central fringe when formed by a 10 lines/mm diffraction grating on a screen 5 meters away....
White light is incident on a block of glass that has index of refraction n = 1.816 for violet light and n = 1.800 for red light. The thickness of the block is L = 29 cm. If the angle of incidence is 30 degrees, what is the distance x between the violet and red rays when they emerge from the glass? Take the index of refraction of air to be 1.00. AL- Answer: cm Check Incorrect Marks for this...
7. An object is placed at a distance of 80 cm left of a converging lens with a focal length of 30 cm. . Calculate the image distance. Is the image virtual or real? If the object is 8 cm tall, what is the size of the image? A diverging lens with the same focal length is placed 10 cm right of the first lens. Determine final image position and magnification. 8. A light ray strikes a flat piece of...
A) An object in medium with index of refraction ni emits light towards an observer in a second medium with index of refraction n2. Assume n2 <ni and 0 = 45°. Draw the complete trajectories of seven rays that leave the object heading toward the seven dots on the surface. Where does the observer in medium 2 appear to see the object? Use at least two light rays to locate the image point. B) On the diagram are shown two...
07. When a light ray in air enters glass with index of refraction 1.60, what is the greatest angle of refraction that can occur? Q3: A mira image ": nrm. If an object is placed 10 cm in front of the mirror, where will the nu rear or virtual?
The left end of a long glass rod 8.20 cm in diameter, with an index of refraction 1.58, is ground and polished to a convex hemispherical surface with a radius of 4.10 cm . An object in the form of an arrow 1.50 mm tall, at right angles to the axis of the rod, is located on the axis 24.0 cmto the left of the vertex of the convex surface. 1) Part C Is the image erect or inverted?
