Because it collects and focuses as much as possible of the light from the bulb and send it out as a fairly tight beam in one direction only.
Convex mirrors are also curved mirrors, but the silvered surface bulges outward instead of inward, as with the concave spherical mirror. As with all mirrors, the angle of incidence of a ray of light is equal to the angle of reflection with respect to a normal on the surface. On a curved surface the normal changes with the curvature. Therefore, the light rays will diverge from the object. If the rays of light are extrapolated back to the point where they converge, this will be the point where the image is formed. For reflections off a convex mirror, the image is virtual and upright. Use of Convex Mirrors: Convex mirrors are often used in car wing-mirrors because they have a greater field of view than a similar plane mirror. However the greater field of view is at the expense of making objects seem further away than they are in reality. Hence the expression seen etched on to the mirrors, 'Objects in Mirror are Closer than they Appear'. Concave mirrors are also used as security mirrors as they enable the viewer to see over a greater region of space another use for this mirror is used in making sunglasses and telescopes. bet you didn't know that did u ???
Fog forms on bathroom mirrors and car windows when the water vapor in the air condenses on the glass. This is due to the temperature difference between the glass and the air.
Reflecting road lights were inspired by the need to improve road safety by increasing visibility during nighttime and adverse weather conditions. The invention aimed to make roads and vehicles more visible to drivers, reducing the risk of accidents and enhancing overall road safety. Reflecting road lights also help guide drivers and improve traffic flow, particularly in low-light situations.
Not using bright lights, turning off music/radio so you can hear traffic at intersections, opening windows at intersections, getting fog lights on the car, and using only low beans on the car.
Convex mirrors are fixed on sharp turns in mountain roads to improve visibility for drivers. They provide a wider field of view, allowing drivers to see around corners and spot oncoming vehicles or potential hazards. This helps to increase safety by reducing the risk of accidents on narrow and winding mountain roads.
Basically shaving mirror, make-up mirror, car head lights.
The Rear view mirrors are convex The Headlights are concave
Concave Mirrors
Car headlight mirrors are typically concave. Concave mirrors are designed to focus light in a specific direction, providing better visibility for drivers at night.
-A car's headlight, reflector lamps. -Concave mirrors can be used as makeup or shaving mirrors because an enlarged image can be obtained using a concave image. -Concave mirrors can also be mirrors used for dentists to see an enlarged image of a tooth.
Concave mirrors are commonly used in car headlights to focus light beams and increase visibility. They are also used in makeup mirrors to magnify images for better visibility. Additionally, concave mirrors are used in reflecting telescopes to gather and focus light for enhanced viewing of distant objects.
To reflect a larger amount of... stuff.
Concave mirrors are found in various applications such as solar cookers, satellite dishes, makeup mirrors, and car headlights. They are also used in reflecting telescopes and in medical instruments like otoscopes and dental mirrors.
the simplest example would be the side mirrors in a car
Concave mirrors are used in reflecting telescopes, makeup mirrors, and headlights to focus light rays. Convex mirrors are used in security mirrors, wide-angle rearview mirrors in cars, and magnifying glasses to provide a wider field of view or to reduce image distortion.
They are used as dentists' mirrrors to magnify the image of a patients teeth to faciliate the examination.They are used as cosmetic mirrors to have an enlarged view of the face to apply make up or to shaveUsed as source of fire.They are useful in projector lamps.They are used in telescopes.headlights of carsreflectors in flash-lights
It directs the beam a certain way.
