3 cards from this section. Quick, good the night before a test.
What is the magnification of an image that is 12 cm tall if the object is 4 cm tall?
Use the formula \\( m = \\frac{v}{u} \\).
If a concave mirror gives a negative magnification of -1.5, what can we say about the image?
Consider both the answer and the meaning of negative magnification.
What does a negative magnification value indicate?
Think about signs in math!
True or False: A convex lens only produces real images.
Consider the object distance relative to the focal point.
A scientist uses a microscope with a 10x objective lens and a 40x eyepiece. If she views an object that is 2 mm tall, what is the height of the image produced?
Multiply the two magnifications together.
How would the magnification change if the object distance is increased while observing through a concave mirror?
Consider the changes in the distance of the object relative to the focal point.
