Here ,
for the image to be virtual
let the focal length is f
1/f = 1/di + 1/do
NOw, for di to be negative
1/di = 1/f - 1/do
do must be smaller than f
the object must be placed closer than focal length from the lens
Under what conditiorn will a convex lens produce a virtual image from a real object?
Based on the image, is the image real/virtual, inverted/upright,
and what is the magnification?
Object F F Plane mirror Convex lens
A convex (converging) lens produces a real, inverted image of an object that is magnified 2.30 times when the object is 25.0 cm from the lens. What is the focal length of the lens?
A convex (converging) lens produces a real, inverted image of an object that is magnified 2.20 times when the object is 23.0 cm from the lens. What is the focal length of the lens?
In a converging (convex) lens, positive magnification m means the image is virtual, erect and lies in the same side of the object. positive magnification m means the image is real, inverted, and on the same side of the object. negative magnification m means the image is virtual, erect, and on the opposite side of the object.
lens A had a real object whereas lens C had a virtual object. what
do you notice is the difference between the incident rays
approaching each lens.
please answer the full question and explain.
Real object for lens A Real image for lens A, virtual object for lens C Is shift in point of convergence Lens A s' Lens C Real image for lens C
You are provided a convex (+) thin lens and an object where a real image at a focal length f=f is found. Find the minimum distance possible from the object to the image using the focal length. Draw a ray sketch and use the thins lens equation.
A diverging lens is used to get a virtual and magnified image of a real object. Where is the object possibly located? (A) Between the lens and its virtual focal point. (B) At the lens's virtual focal point (C) Between the lens's virtual focal point and its radius of curvature (2f). (D) At the radius of curvature (2f) (E) I is not possible to obtain the described image with a diverging lens

64. . An object is a distance f/2 from a convex lens. (a) Use a ray diagram to find the approximate location of the image. (b) Is the image upright or inverted? (c) Is the image real or virtual? Explain.
An object is placed 15.0 cm to the left of a convex (converging) lens of focal length 20.0 cm. The image of this object is located (Figure out if the image is real or virtual, it will help to locate the image] O 60.0 cm to the left of the lens. O 60.0 cm to the right of the lens. O 8.57 cm to the right of the lens. O 8.57 cm to the left of the lens. Question 8...
