Choose true or false for each statement regarding concave mirrors. 8 If an object is placed 3.9 cm from a concave mirror with f = 4 cm, then its %3D image will be reduced and real. O If an object is placed 7.9 cm from a concave mirror with f = 4 cm, then its image will be enlarged and real. O A concave mirror produces an enlarged real image when the object is placed just beyond its focal point (Region 2).

Part A How far apart are an object and an image formed by an 95 -cm -focal-length converging lens if the image is 3.20 x larger than the object and is real? Express your answer using two significant figures. ? do + d; = Cim

HW7 Q4 An object with a height of 40cm is placed 2.4m in front of a convex mirror with a focal length of -0.75m. Determine the approximate location of the image using a ray diagram. Express your answer using two significant figures.   Determine the approximate size of the image using a ray diagram. Express your answer using two significant figures. Is the image upright or inverted?

Select all statement that are true regarding spherical mirrors and the images that they produce. (4 are correct. Note that choosing an incorrect statment will result in a deduction) O The image formed by a single interaction with a convex spherical mirror will always yeild a virtual image. O The image produced by a single interaction with a concave spherical mirror will always be larger than the object. O Virtual images are always formed on the backside of a mirror. O The image produced by a single interaction with a convex spherical mirror will always be smaller than the object. O The image produced by a single interaction with a concave spherical mirror will always be smaller than the object. O Regarding a convex spherical mirror; if an upright object is located within the focal point of the mirror, the image will be upright as well. O The image produced by a single interaction with a convex spherical mirror will always be larger than the object. O Regarding a concave spherical…

An object stands on the common central axis of two thin, symmetric lenses. The object is placed 15.0 cm in front of the first lens (converging lens) whose focal length is 10.0 cm. The second lens is a diverging lens whose focal length is also 12.0 cm. The distance between the lenses is 40.0 cm. a.) Determine the characteristics of the final image by using thin-lens and magnification equations. Give your reasoning. b.) Find the location of the final image by using ray diagrams (sketch the rays clearly). Object f₁ 15 cm 1st Lens f₁ 40 cm 420 2nd Lens
