When you place a saltshaker 26 cm from your magnifying glass, a real image forms 28 cm from the lens on the opposite side. You can see this image dimly on a sheet of paper. What is the focal length of the magnifying glass?
When you place a saltshaker 44 cm from your magnifying glass, a real image forms 40 cm from the lens on the opposite side. You can see this image dimly on a sheet of paper. What is the focal length of the magnifying glass? Please explain step by step. Thanks!
You hold a magnifying glass up to a flower. The magnifying glass has a focal length of 6.0 cm and you hold the flower 4.0 cm from the glass. What is the distance from the glass that you see the image? What is the magnification? Use a scaled ray tracing diagram! Focal point Virtual image Object
Shaving/makeup mirrors typically have one flat and one concave (magnifying) surface. You find that you can project a magnified image of a lightbulb onto the wall of your bathroom if you hold the mirror 2.0 m from the bulb and 3.5 m from the wall. What is the magnification of the image? What is the focal length of the mirror? You have a semicircular disk of glass with an index of refraction of n = 1.57. Find the incident angle...
Shaving/make-up mirrors typically have one flat and one concave (magnifying) surface. You find that you can project a magnified image of a light bulb onto the wall of your bathroom if you hold the mirror 1.71 m from the bulb and 3.64 m from the wall. What is the magnification of the image? What is the focal length of the mirror?
When a person holds a magnifying glass 8.0 cm away from an object that is 2.0 cm wide, she sees a virtual image of the object, which is 6.0 cm wide. What is the focal length of the magnifying glass? Provide a drawing using the ray tracing rules.
A doctor examines a mole with a 17.0 cm focal length magnifying glass held 14.0 cm from the mole. (a) Where is the image? (Enter the image distance in meters. Include the sign of the value in your answer.) m (b) What is its magnification? (c) How big in millimeters is the image of a 4.70 mm diameter mole? mm
A doctor examines a mole with a 14.5 cm focal length magnifying glass held 14.0 cm from the mole. (a) Where is the image? (Enter the image distance in meters. Include the sign of the value in your answer.) m (b) What is its magnification? (c) How big in millimeters is the image of a 4.50 mm diameter mole? mm
A doctor examines a mole with a 15.6 cm focal length magnifying glass held 11.7 cm from the mole. (a) How far is the image from the lens? Can you write the thin lens equation which gives a relationship between the focal length of a lens, the object distance, and the image distance? If the image distance is negative, what can you conclude about the image? cm Is the image real or virtual? realvirtual (b) What is its magnification? (c)...
Shaving/makeup mirrors typically have one flat and one concave (magnifying) surface. You find that you can project a magnified image of a lightbulb onto the wall of your bathroom if you hold the mirror 2.0 m from the bulb and 3.3 m from the wall. Part A What is the magnification of the image? Express your answer using two significant figures. m = Part B Is the image erect or inverted? Is the image erect or inverted? Part C What...
