What is the magnification produced by a concave mirror when the object is placed at the focus? (2019)
Step 1: Understand what a concave mirror is. A concave mirror is a mirror that curves inward, like a bowl.
Step 2: Know where the focus is. The focus is a point in front of the mirror where light rays that are parallel to the mirror's axis converge.
Step 3: Place the object at the focus of the concave mirror. This means the object is located at the point where light rays meet.
Step 4: Determine where the image is formed. When the object is at the focus, the light rays reflect off the mirror and travel parallel to the axis.
Step 5: Understand what happens to these parallel rays. Since they are parallel, they do not converge to form a real image; instead, they appear to diverge from a point far away.
Step 6: Conclude that the image is formed at infinity. This means the image cannot be seen at a specific location.
Step 7: Define magnification. Magnification is the ratio of the height of the image to the height of the object.
Step 8: Since the image is at infinity, the magnification is considered infinite.
