A diverging lens with a focal length of -13 cm is placed 13 cm to the right of a converging lens with a focal length of 19 cm . An object is placed 33 cm to the left of the converging lens. Express your answer using two significant figures. di (d subscript i) = ___ cm from the diverging lens
A magnifying glass is a single convex lens with a focal length of ff = 13.0 cm . What is the angular magnification when this lens forms a (virtual) image at the person's near point (assumed to be 25 cm)? M =
A microscope has an objective lens with a focal length of 10.0 mm . A small object is placed 0.90 mm beyond the focal point of the objective lens. If an eyepiece with a focal length of 2.5 cm is used, with a final image at infinity, what will be the overall angular magnification of the object? Express your answer using two significant figures.
The focal length of a lens is 4.5 cm. Calculate the maximum angular magnification of a simple magnifier when the image is formed at the normal near point of the eye.
The focal length of a lens is 4.6 cm. Calculate the maximum angular magnification of a simple magnifier when the image is formed at the normal near point of the eye.
