Convex spherical mirrors always produce images that are upright, virtual, located behind the mirror and reduced in size. The location of the object relative to the mirror does not change these image qualities.Know More
Convex mirrors are called diverging mirrors because they cause incident light originating from the same point to divergently reflect off the mirror surface. Light rays that diverge off a convex mirror never intersect on the object side of the mirror. These properties mean that convex mirrors cannot be used to focus light or project an image on a screen.
The virtual images that convex mirrors form widen the field of view, enabling their usage as passenger-side vehicular mirrors. Objects in such mirrors appearing further away than they truly are can be attributed to the distorting effect that convex mirrors have on the image and consequently on the driver’s distance perception. Convex mirrors are often found in the hallways of hotels, hospitals, schools and apartment buildings, where they are mounted at blind corners, sharp turns and orthogonal intersections. People making these turns can look at the mirror to see around the bend of the hallway and avoid collisions. Such mounted safety mirrors are also used on roads and in alleys to facilitate pedestrian and motorist safety.Learn more about Shapes
Technically, a pendulum can be created with an object of any weight or shape attached to the end of a rod or string. However, a spherical object is preferred because it can be most easily assumed that the center of mass is closest to the pivot's end, thereby limiting variables.Full Answer >
According to Scientific American, all objects reflect light, but very few reflect light in a way that allows one to see an image like that seen in a mirror. This is due to a certain type of light reflection called specular reflection. This type of reflection doesn't scatter light. Instead, it directs light directly back toward the observer, which allows for a clear image.Full Answer >
Specular reflection allows a person to look like themselves in a mirror, whereas photography uses a convex lens to slow down beams of light to recreate a "real" image of whatever is in front of the lens. Both mirrors and photography make use of rays of light bouncing off a surface to create a transient or permanent image respectively.Full Answer >
The image in a plane mirror is right side up and full size. It is a horizontal reverse of the object and is called a virtual image. The object's distance from the mirror and the image's distance from the point of reflection are equal.Full Answer >
