The image distance is s=3m and the height of the object is h=5 mm Determine 1- Draw the reflected rays and the image formed 2- calculate the magnification "m" of image 3- Determine The height h of the image 4- Determine the Radius "R" Object h = 5,00 mm Mirror Optlo axls K10.0 cm> KR = ?-

mirror/ If a concave mirror/convex concave lens/convex lens has a radius of 4 cm and the height of the object is 1 cm and the distance of the object is 1 cm, 2 cm, 3 cm, 4 cm and 5 cm from the optical center point then specify: a. Draw a picture of the shadow formation process and the nature of the resulting shadow! b. Shadow distance and image height (The calculation results must be close to / equal to the results of measurements using a ruler)

A lens produces an upright virtual image between the lens and the focal length of the lens, on the same side of the lens as where the object is located, when the object is outside the focal length of the lens. The focal length of the lens is 15cm and the image is 0.3 times the size of the object. a) Determine the type of lens. b) Determine the distance of the object from the lens. c) Determine the distance of the image from the lens

Application For a camera with a lens of fixed focal length F focus on an object located at a distance x from the lens, the film must be placed at a distance y behind the lens, where F, x, and y are related by 1 + 1 y F Suppose the camera has a 55-mm lens (F=55). A. Express y as a function of x and graph the function. B. What happens to the focusing distance y as the object moves far away from the lens? C. What happens to the focusing distance y as the object moves closer to the lens?

Solve these problems: 1.- A ray of light arrives at an angle of 40° travelling through the air when it enters the water. Determine the speed of light in water and the angle of refraction in water. 2.-A pencil is placed 30 cm from a converging lens, with a focal length of 20 cm. Determine the size of the Determine the size of the pencil in the image if the real pencil measures 8 cm and obtain the distance from the lens to the virtual image. 3.- A luminous ray arrives at the surface of separation between the air and the glass, with an angle of incidence of 60°.  Calculate the angle of refraction.  It is final delivery(~_~;) I would very grateful for your help!

15. When we look at an object, it is projected on the retina through the pupil. The distances from the pupil to the top and bottom of the object are congruent and the distances from the pupil to the top and bottom of the image on the retina are congruent. Are the triangles formed between the object and the pupil and the object and the image similar? Explain your reasoning. A C Object Image on Retina E US

What is the difference between a converging lens and diverging lens? Explain.

a.) Draw a simple version of the human eye looking at the sun (never look at the sun yourself!), showing the lens and the retina. Label s, s’, and f.     b.) If the distance between the lens and the retina is around 2 cm, relabel s, s’, and f with their exact distances.     c.) Why do we need a lens in the eye to view distant objects?

A person is having nearsightedness vision defect because, a. the lens of the eye become too weak b. the eye become too long c. the eye become too short d. no vision

What is the focal length and power of the eye lens when viewing an object 65 cm away? Consider the lens-to-retina distance to be 0.02 m. a) focal length of the lens in meter b) power of the lens in diopter

Macmillan Learning You have a convex lens with a focal length of 8.6 cm. You want to use it to project an image from your cell phone's screen onto a wall that is 181 cm away from the lens. How big the image would be on the wall compared to the image on your phone's screen, i.e. what is the magnification? Hint: Combine the lens equation with the equation for magnification to eliminate do. Make sure to include the correct sign in your answer. magnification: MacBook Pro

1 a) Draw a picture that shows the sun's rays passing through a convex glass lens. b.) Label your diagram with the object to lens distance s, the image to lens distance s', and the focal length fof the lens. Why can't you burn a leaf using sunlight with a diverging lens, or with no lens at all?
