To a fish, the 4.20 mm thick aquarium walls appear to be only 3.80 mm thick....
A soap bubble with walls 421 nm thick floats in air. 1) If this bubble is illuminated perpendicularly with sunlight, what wavelength of visible light will be absent in the reflected light? Assume that the index of refraction of the soap film is 1.33.
A soap bubble with walls 380 nm thick floats in air. If this bubble is illuminated perpendicularly with sunlight, what wavelength of visible light will be absent in the reflected light? Assume that the index of refraction of the soap film is 1.33. What color will be absent in the reflected light?
A soap bubble with walls 382 nm thick floats in air. Part A If this bubble is illuminated perpendicularly with sunlight, what wavelength of visible light will be absent in the reflected light? Assume that the index of refraction of the soap film is 1.33. Part B What color will be absent in the reflected light?
(a) A goldfish is swimming at 4.80 cm/s toward the front wall of a rectangular aquarium. What is the apparent speed (in cm/s) of the fish measured by an observer looking in from outside the front wall of the tank? (b) What If? The fish is now gently transferred to a spherical bowl with a radius of curvature R = 30.0 cm. If it again swims at 4.80 cm/s along a radial line toward the outside of the bowl, what is...
12,/A cylindrical copper kettle has a 10 e radius and walls that are 2.0 mm thick. The that are 2.0 mm thick. The temperature of the outside surface (in contact with the stove) is 102.0°C and the inside wall of the kettle is at 100.0°C. At what rate is energy being transferred through the bottom of the kettle? And by what method of energy transfer? The thermal conductivity of copper is k 397 J/(s-m·°C)
someone threw a fish into your pool and it miraculously survived not only the shock of being thrown but apparently this ugly fish can breath your chlorinated pool water. you see the fish by sunlight that reflects off the fish and refracts at the water-air interface. if the light from the fish to your eye strikes the water -air interface with an angle of incidence of Oa 17.90 degree. what is the angle of refraction of the ray in air?...
A glass plate 2.50 mm thick, with an index of refraction of 1.40, is placed between a source of light with wavelength 540 nm (in vacuum) and a screen. The source is 1.80 cm from the screen. How many wavelengths are there between the source and the screen?
One may assume the rays relevant for image formation are making small angles relative to the normals of the glass. The position of the coral is meant to be the actual physical position of the fish. My professor told us we’d have to use Snell’s Law in an unusual way when solving this problem. 1. You are visiting the Adventure AquariumTM in Camden, NJTM enjoying some time relaxing and looking at fish. One fish is floating near a fixed piece...
1. The inner core of an optical fiber has a diameter of 0.1 mm and an index of refraction of n1 = 1.5. The outer core of the fiber has an index of refraction of n2 = 1.49. 12 = 1.49 ni = 1.5 n2 = 1.49 (a) (7 points) Coming from air, what is the largest angle relative to the aris of the fiber for which light is totally internally reflected in the fiber? (b) (6 points) I want...
Building contractors often install double-glazed windows to prevent thermal energy (heat) from entering or exiting a building. In addition to being effective insulators, such windows present interesting optical effects.In the figure, a double-glazed window consists of two identical panes of glass (ng = 1.50), each yg = 32.0 mm thick, separated by an air gap of ya = 25.6 mm. If light incident on the glass makes an angle of φ = 40.00° with respect to the glass, find the...
