An object placed 32.4 cm in front of the mirror has a real image 58.7 cm...
The real image of a concave mirror is four times as large as the object. (a) Determine the image distance for an object that is 22.6 cm from the mirror. (Include the appropriate positive or negative sign.) (b) Determine the focal length of the mirror. (Include the appropriate positive or negative sign.)
number 3 please 2. Calculate the image distance from the equation-+-=- PS: for a concave mirror, the focal length is taken to be positive (); for a convex mirror, the focal length is taken to be negative ). The object distance do is taken to be positive in either case. The sign convention is as Tollows: If di is positive, the image is real, and if di is negative, the image is virtual. 3. How might you determine the focal...
(a) Find the focal length of a concave mirror if an object placed 40 cm in front of the mirror has a real image 80 cm from the the mirror. (b) Where will the image be if the object is moved to a point 20 cm from the mirror? (c) What type will this image be? (a) Find the focal length of a concave mirror if an object placed 40 cm in front of the mirror has a real image...
If when an object is placed 12.0 cm in front of a mirror the image is located 20.7 cm behind the mirror, determine the following. (a) the focal length of the mirror What is the relationship between the focal length, image distance, and object distance for a spherical mirror? What is the sign associated with the image distance of an image behind the mirror? cm (b) if the mirror is concave or convex concave convex
An object is placed 11 cm in front of a concave mirror whose focal length is 17 cm. The object is 3.2 cm tall. Determine (a) the location of the image, taking a real image as a positive value and a virtual image as a negative value. (b) Determine the height of the image, where an upright image will have a positive height and an inverted image will have a negative height. Object
An object is placed 12 cm in front of a concave mirror whose focal length is 17 cm. The object is 2.7 cm tall. Determine (a) the location of the image, taking a real image as a positive value and a virtual image as a negative value. (b) Determine the height of the image, where an upright image will have a positive height and an inverted image will have a negative height.
32. The image of an object placed 20 cm in front of a concave mirror of focal length 10 cm will be A. real and inverted. B. real and erect. C. virtual and inverted. D. virtual and erect. The answer is A instead of C, can you explain why? Thanks!
A convex mirror produces a virtual image that is one quarter the size of the object. (a) Determine the image distance if the object is 37.0 cm in front of the mirror. (Include the appropriate positive or negative sign.) cm (b) Determine the focal length of the mirror. (Include the appropriate positive or negative sign.) cm A convex mirror produces a virtual image that is one quarter the size of the object. cm (b) Determine the focal length of the...
An object is placed 24.1 cm in front of a convex mirror of focal length 50 cm. Note: Do convex mirrors have a positive or negative focal length? What is its image position? Answer in units of cm. The magnification of the image in the previ- ous question is: With the arrangement discussed above, the image is: 1. virtual, inverted, smaller than object 2. real, erect, smaller than object 3. real, inverted, bigger than object 4. real, erect, bigger than...
An object is placed in front of a concave mirror, at a distance inside the focal point (object distance < f). The type and location of the image formed is A. a real image in front of the mirror. B. a virtual image behind the mirror. C. a real image behind the mirror. D. a virtual image in front of the mirror.
