Question 7: Now imagine that you are working with a double concave lens. You can convert the convex lens to a double concave by moving the point labeled focus' to the other side of the lens. Create the following scenario f = -2.0, object of height họ = 1 unit is placed at x = -8 and the object distance is do = 8 units. What is the images distance, the magnification, type of image formed and the orientation of the image? Why is this image called virtual?

Transcribed Image Text:**Lens Equation: Lab Activity**
The relationship between the object distance \(d_o\), image distance \(d_i\), and the focal length \(f\) can be modeled by the thin lens equation:
\[
\frac{1}{d_o} + \frac{1}{d_i} = \frac{1}{f}
\]
A thin lens is a lens where the width of the lens is a lot smaller than the diameter of the lens.
**Double convex lens:** Assume that the object distance \(d_o\) is positive if it’s to the left of the lens, the image distance \(d_i\) is positive if it’s to the right of the lens, the focal point is positive if it is on the other side of the lens as the object.
**Double concave lens:** Assume that the object distance \(d_o\) is positive if it’s to the left of the lens, the image distance \(d_i\) is negative if it’s on the same side of the lens, and the focal point is negative if it’s on the same side as the object.
**Focal length** is positive if working with a double convex lens and negative if working with a double concave lens.
The lens magnification can be described using the formula \(m = -\frac{h_i}{h_o} = -\frac{d_i}{d_o}\) where \(h_o\) is the object’s height, and \(h_i\) is the image's height.
