- Asap plzzzzAn olive is at the bottom of a glass of alcohol (n = 1.36). 6.78 cm beneath the surface. Above the alcohol is air. To a person in the air, who is directly above the olive, what is the apparent depth d' of the olive. d'= Number UnitsIn a field trip, the students stopped by an aquarium made of plastic. The surface of the aquarium was curved back (convex) with a uniform thickness and a radius of curvature of 3.2 m. 11 A goldfish and a blackfish were located at 10 cm and 20 cm from the front of the wall respectively (nwater = 1.33, nair =1.00). a) Locate the images of both fishes. b) Calculate and compare the magnification of the two cases.
- A 2.5 cm-tall object stands in front of a converging lens. It is desired that a virtual image 2.6 times larger than the object be formed by the lens. How far from the lens (in cm) must the object be placed to accomplish this task, if the final image is located 13 cm from the lens? cm?You unconsciously estimate the distance to an object from the angle it subtends in your field of view. This angle 0 in radians is related to the linear height of the object h and to the distance d by 0= h/d. Assume that you are driving a car and that another car, 1.50 m high, is 22.0 m behind you. KTO & $3 m (d) What angle does the image subtend at your eyes? rad (e) Based on its angular size, how far away does the following car appear to be? m 0 1900 Per Works Inc OBJECTS IN MIRROR ARE CLOSER THAN THEY APPEAR vestest by Creators Syndicate The Far Side by Gary Larson 1985 FarWorks, Inc.

Forthis problem give all distances in centimeters. Using formulas for mirror calculate:a) The position of the image; b) Magnification; c) Size of the image.By using results of calculations describe the image:real/virtual, upright/inverted, increased/decreasedDraw a diagram of principal rays showing the formation of the image, showfocal points. Describe the image and compare it with results of calculations.
- An olive is at the bottom of a glass of alcohol (n = 1.36), 6.00 cm beneath the surface. Above the alcohol is air. To a person in the air, who is directly above the olive, what is the apparent depth d' of the olive. d' = Number i Unitsa) What is the apparent depth of an object that is 1.5 meters below the surface of water? (b) Sketch a rough ray diagram showing the object and image below the water's surface. c. When observing the convex side of a shiny spoon, which is approximately spherical with a radius of 5.0 cm, calculate the location of the your image be if you are 18 cm away from it?
