An object is placed 40 cm in front of a concave mirror that has a focal length of 30 cm. What is the image distance?
Two concave mirrors are placed facing each other. An object is placed between them. Describe the final image characteristics.
What type of image is always formed by a convex mirror?
An object is placed 20 cm in front of a convex mirror with a focal length of -10 cm. Find the image distance and magnification.
A person walks towards a plane mirror at a speed of 2 m/s. What is the speed of the person relative to their image?
Which of the following ray diagrams correctly depicts the image formation by a concave mirror when the object is placed between the focal point and the mirror?
A concave mirror is used to form an image of an object placed at a very large distance (essentially at infinity). What type of image is formed?
