bcause when light source placed at focus of the mirror, after flashing the light form the source to the mirror after reflection a straight parallel beam of light emerges which makes the street bright
The concave shape focuses the light into a narrow beam. If the mirror was convex, the light would be spread out - useless for searching into any distance.
A concave mirror is a reflective surface that curves inward, like the interior of a bowl. It can reflect light to converge at a focal point in front of the mirror. Concave mirrors are commonly used in reflecting telescopes and makeup mirrors.
A concave mirror is used in a solar cooker to concentrate sunlight onto a central point, where the cooking vessel is placed. This focusing of sunlight helps to increase the temperature inside the solar cooker for cooking food.
A concave mirror is a reflective surface that curves inward like the inside of a bowl. It can reflect and focus light to create real or virtual images depending on the object's position relative to the mirror's focal point. Concave mirrors are often used in reflecting telescopes and cosmetic mirrors.
A concave mirror magnifies the image of an item close to it. This type of mirror has a curved surface that causes light rays to converge, creating a magnified image of objects placed near it. Concave mirrors are commonly used in makeup mirrors and telescopes.
A street light mirror is typically concave. Concave mirrors are used in street lights to reflect light downwards and maximize illumination on the street below. The curved surface of the concave mirror helps to focus the light in a specific direction.
Basically shaving mirror, make-up mirror, car head lights.
The concave shape focuses the light into a narrow beam. If the mirror was convex, the light would be spread out - useless for searching into any distance.
A shaving mirror is concave as it used used to magnify the image.
concave mirror is a solar device
Concave mirrors are used in flood lights because they can reflect light in a concentrated manner. This helps to direct more light in a specific direction, increasing the brightness and coverage of the light. The curved shape of the concave mirror allows for better focusing and control of the light output.
plano concave
because the mirror used is concave mirror.
Shaving mirror, mirror used by dentists.
A concave mirror.
A concave mirror is used in headlights and searchlights as it can reflect and focus light beams to a single point, creating a strong and concentrated beam that can travel long distances. The mirror's shape allows it to gather light from a wide area and direct it in a specific direction, increasing the reach and intensity of the light projection.
Concave mirrors are used in telescopes. Convex mirrors are used as side-view mirrors in cars.
