Since the image is behind the mirror, the distance is considered positive.
The study of mirrors is one of the fundamental topics in physics.
Example of Calculating the Magnification of a Concave Mirror - Real Image If a 4 mm tall rock is placed in front of a concave mirror and its inverted image is 3 mm tall, what is the magnification of the mirror rounded to two decimal places? In such cases, a real image is formed.
Using a straight edge, accurately draw one ray so that it passes exactly through the focal point on the way to the mirror.
Did you know that this precious camera contains a convex lens? Some can be enlarged while others can be shrunk in size.
A sample activity from the datasheet is given below.
