This article explains what convex mirrors are and how they work. It includes where they are most commonly found, common names and the use of convex mirrors in our everyday lives.
The curved mirror was first invented in 1786 by English Physicist Thomas Jefferson. It took him forty years to find out the science behind why his image was distorted.
Curved mirrors are used all around us. In refracting telescopes there are 2 convex lenses. These lenses bend light inward to make the object seem bigger. In reflecting telescopes there is a concave lens. The concave mirror also bends the light inward but in a different way. The concave mirror reflects the light instead of bending it as it passes through, like the convex mirror.
Another name for concave mirror is converging mirror because it can bring incoming light rays together. This gives it a great use in collecting energy because it can collect light rays into one concentrated focal light. Thus, you may be able to see concave mirrors in solar furnace and oven, which is used to collect sunlight and transformed it into heat energy.
This article discusses a new side mirror for cars that do not distort the size of the objects as much. This allows for better judgment of distance from objects.
Curved mirrors have taken part in a lot of researches throughout the years, simply by taking a part in microscopes. Without the concave mirror that exists in microscopes, cells and specimens would be much more challenging to discover. The mirror collects light from the lamp and shines it onto the slide so it can be viewed through the magnification lens.
Concave mirrors can sometimes be blurry and fuzzy. This is why they are used in fun houses. They can change the image to inverted, or even stretch you out to look a little bit wider. Convex mirrors on the other hand, make the image look focused and clear.
This article talks about concave mirrors and how they are effective in our every day lives. Like car headlights and how they help us when driving. Microscopes and telescopes also use concave mirrors as images appear much larger in a concave mirror than a convex mirror.
CPV is a photovoltaic technology that generates electricity from sunlight. Lenses or curved mirrors are used to focus solar light on small, highly efficient solar cells.They enable solar modules to remain in the best position to accumulate maximum energy from the sun. The application of tracking technology allows solar panels to follow the movement of the sun and increase electricity production as compared to a stationary array. Solar trackers are attached to solar panels to adjust their positioning against the daily passage of the sun throughout the year as the weather and seasons change.
This article talks about newly discovered facts about scallop eyes which were not known to be as complex as now discovered. We have now found out that their eyes are convex mirrors similar to teloscopes used to focus all they see to the back of their retina. However, each scallop has around 200 eyes so scientists are still trying to figure out how they all work together
In parking garages, the use of curved mirrors are extremely important when vehicles come to corners of the garage. Since seeing behind the corners of the garage are extremely hard to see, convex mirrors are used, so that you can see behind the corner you are heading, so you don't crash into incoming vehicles that are coming towards you.
This article talks curved mirrors such as concave and convex mirrors. It talks about how a convex mirror is a good security device for store owners so that the owner can see large portions of the store. It also talks about how concave images cannot be projected on a screen because they are virtual images. Also, it talks about how the spoon is both a convex and a concave mirror.
This article details the creation of the world's largest convex mirror. It weighs over 3.5 tons and measures 14 feet in diameter. One of the most interesting parts of the manufacturing process was the cool down period. The mirror took around 1 year to cool down to a temperature that was usable. The reason it took so long was because it was actually placed in a specially designed climate controlled container, where the temperature was very slowly lowered to prevent any stresses from developing in the material. The mirror will be used in the Extremely Large Telescope in Europe, which is due to be completed in 2024.
This article talks about how funhouse mirrors work through curved mirrors. Funhouse mirrors are mirrors that show many variations of yourself whether that be very tall or very short. They use convex and concave mirrors to alter the image shown. They could use either or both. These mirrors are different from plane mirrors because they reflect light differently which makes the image appear different to us.
The giant combination mirror that will collect light for the Large Synoptic Survey Telescope (LSST) has arrived at the summit of the Cerro Pachón mountain ridge in Chile, bringing “first light” at the observatory at step closer. The 8.4 meter-diameter “M1M3” component comprises both the primary and tertiary optic for the telescope, which is being built to create a vast catalog of celestial objects. “Combining two astronomical mirrors with different curvatures into one surface had not been done before, but it is this unique design that will enable LSST to combine speed with a crisp, wide field of view,” says the organization. The M1M3 optic joins the 3.4 meter-diameter secondary mirror - said to be the largest convex-shaped mirror ever manufactured - at the observatory site. Chief scientist Tony Tyson said: “Combining the mirrors into two mirrors fabricated on the same Pyrex blank creates a 10-square-degree field of view with very low distortion. This enables an unprecedented broad science reach from cosmology to the time domain.”
The Scallop may be just another animal at first glance, but it has around 200 miniature eyes. Inside of the eye contains of a pupil, lens, two retinas, and then a curved mirror with lots of crystals, much unlike the human eye. However, it is much more like the optical lens in a complex microscope. Opticians have begun to study this species to figure out what makes their eyes so special, and potentially if their curved mirror can change position to the body's liking.

This article briefly explains plane mirrors and curve mirrors. In a plane mirror the distance from the object to the mirror is the same as the distance front the image to the mirror. The image is upright and virtual. I’m a convex mirror the image is also virtual and upright. Light rays coming in the direction of the mirror reflect in all directions. The virtual focal point is behind the mirror. Convex mirrors also produce real images. If the object is behind the focal point the object will appear inverted and real and the closer it gets to the mirror past the focal pin the image will be virtual, larger and upright
