How can you tell if something is moving at a constant speed?
How does the image of a concave lens always appear?
How does the image of a concave lens always appear? Plane mirrors, convex mirrors, and diverging lenses will always produce an upright image. A concave mirror and a converging lens will only produce a real image if the object is located beyond the focal point (i.e., more than one focal length away). 5. The image […]
