- When fully dilated, the pupil of a grey cat is approximately 6.75 mm wide. For 650 THz light ("T" stands for "tera" and means 1012), determine the minimum angle that can be resolved for the grey cats eye. Express your answer in degrees. ?min = The diagram below shows a grey parrot looking at two trees. The grey parrot is just able to resolve the two trees. The distance between the grey cat & the trees is 69.6 km. For the ?min you just determined, determine the distance between the two trees. distance between the two trees=You are in your car driving on a highway at 25 m/s when you glance in the passenger-side mirror (a convex mirror with radius of curvature 150 cm) and notice a truck approaching.

VirtualTwo converging lenses with focal lengths of 40 cm and 21 cm are 12 cm apart. A 4.0-cm-tall object is 15 cm in front of the 40-cm-focal-length lens. Part A Calculate the position of the final image (relative to the 21-cm-focal-length lens). Express your answer to two significant figures and include the appropriate units. Enter a positive value if the image is on the other side from the lens and a negative value if the image is on the same side. Submit
- For a concave mirror, if the object distance is less than the focal length, the image is virtual, upright, and enlarged. O True False At least three rays of light are needed in order to find out where the image is formed. O True O False Total interhal reflection can occur when light travels from vacuum to an optical medium with higher index of refraction. O True False The reason that a prism can produce a colorful spectrum from a white light source is that its index of refraction is a function of wavelength.

- A glass sphere (n = 1.50) with a radius of 12.0 cm has a tiny air bubble 4.00 cm above its center. The sphere is viewed looking down along the extended radius containing the bubble. What is the apparent depth of the bubble below the surface of the sphere? 1 Your response differs from the correct answer by more than 10%. Double check your calculations. cmsolve correctly. I will rate accordingly.F1 F2 Figure above shows a thin converging lens in front of a concave spherical mirror with the radius of curvature R = 5.0cm. Assume that the lens focal points F1 and F2 are 5.0 cm from the center of the lens. The lens and mirror are 18.0 cm apart, and an object is placed 7.0cm to the left of the lens. How far from the lens is the position of the final image? State your answer in cm to the nearest 0.1 cm.
