2 cards from this section. Quick, good the night before a test.
What is the relationship between focal length and radius of curvature in a concave mirror?
Remember, the formula connects 'f' to 'R' directly.
What type of image does a convex mirror form?
Think about how light rays behave with a convex surface.
What is the focal length formula for spherical mirrors?
Recall the connection between focal length and radius.
True or False: Concave mirrors always create virtual images.
Think about where the object is placed relative to the focal point.
A convex mirror has a focal length of -20 cm. If an object is placed at a distance of 30 cm, calculate the image distance and describe the nature of the image formed.
Remember that convex mirrors only produce virtual images.
A concave mirror forms a real image of an object placed 15 cm from it. If the mirror's radius of curvature is 40 cm, determine the image distance and nature of the image.
Real images are formed beyond the focal length.
