- If a object is placed between a convex lens and its focal point, the image formed is O virtual and inverted. O virtual and upright. real and inverted. real and upright.A spherical concave lens has a focal length of 50 cm, and an object is placed 25 cm from the lens. Draw a digram. Estimate the image distance Is it real or virtual upright or inverted magnified or reducedA convex lens has a radius of curvature of 20 cm. A 36-cm high object is placed 15 cm in front of the lens. Determine the location, nature, size, and orientation of the formed image.
- A 2.1-cm-tall object is 30 cm to the left of a lens with a focal length of 15 cm. A second lens with a focal length of -5 cm is 45 cm to the right of the first lens. Calculate the distance between the first image and the second lens. Calculate the image height.You are looking through the wall of the aquarium to a fish. Is the fish on the same distance as you see it, further or closer? Make a drawing.a ray diagram for eyeglasses that contain a converging lens. Assume you are looking at a 2 cm tall object that is 4 cm from the lens. The focal length is 3 cm
- You are having trouble reading your cheat sheet during your physics exam because you wrote so small. You foresaw the problem, so you brought a small lens with you to the exam. You hold the lens 6 cm away from the page. The image you see is upright and 2.9 times the size of the writing on the page. where is image formed Is the image real or virtual what is the focal length of the lens are you using a converting lens or a diverging lensA diverging lens has a focal distance of f=0.2 cm. If an object is placed 0.1cm away, What is the image distance? Is the image real or virtual? What is the magnification?An object is placed in front of a diverging lens whose focal length is - 30.7 cm. A virtual image is formed whose height is 0.532 times the object height. How far is the object from the lens?
- Q: You hold up a piece of paper by a lens and see the image of a candle projected on the paper. Is this image real or virtual? Q: Will the projected image show the candle right-side-up or upside-down? Q: You look through a concave (diverging) lens at a candle. Will the image you see be smaller or larger in size than the actual candle?You are a marine biologist and want to pull a star fish out of a tank of water for testing. Looking from the top of the tank, where is the actual starfish compared to the image of the starfish that you see from the surface? Explain.A 3.0 cm tall object is positioned 15.5 cm from a converging lens. The focal length of the lens is 10.5 cm. What is the distance to the image? What is the magnification of the image?
