The critical angle from a particular medium into air is 60.7°. What is the index of refraction for this medium?

Light is incident on water(n=1.33) from air (n=1.001) at an angle of 34°. What is the angle of refraction?

An object is placed 10.1 cm in front of the cornea. (The cornea is thin ans has approximately parallel sides so that the reflection that occurs as light travels from air to cornea to aqueous humor is essentially the same as though the aqueous humor were directly in contact with the air. The aqueous humor has index of refraction n = 1.34 and the radius of curvature of cornea is 7.8 mm.) (a) What is the image distance for the image formed by the cornea alone? (b) The image formed by the cornea serves as an object for the lens. Treat the lens as a thin lens 8 mm behind the cornea. Find the optical power of the lens necessary to form an image on the retina, 25 mm from the center of the lens.

Part of your refraction experiment is on performing a total internal reflection. You measure the critical angle for some oil as 40o. Therefore the refractive index of that oil should be Group of answer choices 2.02 1.56

As shown in the figure, a light beam travels from air, through olive oil, and then into water. If the angle of refraction 0, for the light in the olive oil is 29.6°, determine the angle of incidence 0, in air and the angle of refraction 03 in water. The index of refraction for olive oil is 1.47. 0, = 83 = air n2 oil 13 water

(a) An opaque cylindrical tank with an open top has a diameter of 2.60 m and is completely filled with water. When the afternoon sun reaches an angle of 31.5° above the horizon, sunlight ceases to illuminate any part of the bottom of the tank. How deep is the tank (in m)? 4 Determine how the depth of the tank is related to the angle of refraction for the geometry described in the question. Drawing a diagram may be helpful. Then apply Snell's law to find the angle of refraction and use it to determine the depth of the water in the tank. m (b) What If? On winter solstice in Seattle, the sun reaches a maximum altitude of 19° above the horizon. What would the depth of the tank have to be (in m) for the sun not to illuminate the bottom of the tank on that day? m

A very large piece of clear ice has a cave man frozen inside it. When viewed at an anglefrom the top of the ice the cave man appears to be 1.00 ft below the surface of the ice.What is the actual depth (in units of inches) of the cave man from the top of the ice?The index of refraction of the ice is 1.309   Do NOT use i for the angle of incidence or r for the refracted angle
