In this lesson, we will learn how to relate the sizes and positions of objects to images of them produced by thin convex and concave lenses.
Q1:
An object is placed at the focal point of a thin concave lens. Which of the following statements most correctly describes how the distances from the object to the lens and from the image to the lens compare to each other?
Q2:
A thin convex lens is placed at a distance 𝑑 from an object 2.5 cm in height. On the opposite side of the lens, an image of the object is formed 16 cm from the lens. The distance from the object to the image is 36 cm.
Find 𝑑.
What is the height of the image?
Q3:
An object is placed 2.5 cm from a thin convex lens with a focal length of 3.75 cm. The object is then moved away from the lens.
What is the initial distance between the object and the image?
What is the initial magnification produced by the lens?
How far would the object have to be moved for the lens to produce the same magnification that it produced initially, but with the image now real and inverted?
What is the distance between the initial image formed and the inverted image formed?
