Select from the following for the next two questions:

A virtual, inverted and smaller than the object B real, inverted and smaller than the object C virtual, upright and smaller than the object D real, upright and larger than the object E virtual, upright and larger than the object F real, inverted and larger than the object G virtual, inverted and larger than the object H real, upright and smaller than the object Select from the following for the next two questions: A virtual, inverted and smaller than the object B real, inverted and smaller than the object C virtual, upright and smaller than the objedt D real, upright and larger than the object E virtual, upright and larger than the object F real, inverted and larger than the object G virtual, inverted and larger than the object H real, upright and smaller than the object An object is placed 46.9 cm away from a converging lens. The lens has a focal length of 10.0 cm. Select the statement from the list above which An object is placed 46.9 cm away from a spherical convex mirror. The radius of curvature of the mirror is 20.0 cm. Select the statement from the best describes the image list above which best describes the image

Explanation / Answer

1/v - 1/u = 1/f

u = -7.1
f= -10

therefore calculating v from the above equation
v= -4.152 cm
since v is negative therefore image is virtual

magnification = -v/u = -(-4.152/-7.1) = -0.584 (negative and <1)
therefore image is inverted and smaller than object

therefore answer is F

Virtual inverted and smaller than object
