The figure below shows how a convex lens forms an image of an object on a grid where each small square represents 1 unit of length.
Which point on the figure marks the position of the principal focus of the lens? Choose from: A, B, C, D.
Which two words describe the image?
- Enlarged
- Inverted
- Real
- Upright
- Virtual
Calculate the magnification produced by the lens. Use the equation: magnification=image heightobject height\text{magnification} = \frac{\text{image height}}{\text{object height}}magnification=object heightimage height
Complete the sentence by choosing from: decrease, increase, not change: "As the object is moved further away from the lens, the size of the image will __________."
