To a fish, the 4.20 mm thick aquarium walls appear to be only 3.80 mm thick....
A 610 lines/mm diffraction grating is in an empty aquarium tank. The index of refraction of the glass walls is nglass = 1.50. A helium-neon laser (λ = 633nm) is outside the aquarium. The laser beam passes through the glass wall and illuminates the diffraction grating. What is the first-order diffraction angle of the laser beam? What is the first-order diffraction angle of the laser beam after the aquarium is filled with water ( nwater = 1.33)?
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?
The walls of a soap bubble have about the same index of refraction as that of plain water, n=1.33, There is air both inside and outside the bubble. ( a) What wavelengths ( in air) of visible light is most strongly destroyed from a point on a soap bubble where its wall is 500 nm thick? The visible range is 400nm-700nm.
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...
