How do a concave mirror and convex mirror differ?
A concave mirror, or converging mirror, has a reflecting surface that bulges inward (away from the incident light). A convex mirror, fish eye mirror or diverging mirror, is a curved mirror in which the reflective surface bulges toward the light source.
What will be the brightness of lighted and unlighted buildings which are focused using a concave mirror?
The brightness of lighted buildings focused using a concave mirror will be increased since the mirror can concentrate the light rays onto a specific point. Unlighted buildings will not be affected by the mirror unless an external light source is directed towards them.
Light is refracted and spread out by concave or convex mirrors?
Mirrors reflect light, not refract it. When light hits a concave mirror, it converges to a point known as the focal point. Conversely, light spreading out from a point source will be reflected by a convex mirror, diverging and spreading out.
Which type mirror is used a doctors head mirror?
Convex usually, its used as a light source and not as a magnifier (or imager of any sort).
What would happen if concave mirror is missing in projector?
If the concave mirror is missing in a projector, the light rays from the light source won't be properly focused onto the screen. This would result in a blurry and distorted image being projected, as the concave mirror is responsible for directing and converging the light rays to create a clear image.

Why is concave mirror used in street lights?
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

How does light reflect off a convex and concave?
A parallel light source will reflect off a concave mirror and go through a point inside the curve called the focus. Reflecting from a convex mirror will cause all light to bounce off in a straight line away from a focus point behind the mirror.
Why is a concave mirror used as reflector in torch light?
A concave mirror is used as a reflector in a torch light because it can focus light rays emitted from a point source, such as a bulb, into a parallel beam. This focusing ability enhances the intensity and directionality of the light, allowing for a more concentrated and powerful illumination. Additionally, the shape of the concave mirror ensures that the light is directed forward, maximizing the efficiency of the torch light.

This would result in a blurry and distorted image being projected, as the concave mirror is responsible for directing and converging the light rays to create a clear image.
Why is the flat reflective mirror used while light source come from a lamp while concave mirror is used when light source come from the sun?
A flat reflective mirror is used with a lamp because it reflects light in a straightforward manner, allowing for a direct and uniform illumination of a specific area. In contrast, a concave mirror is employed when the light source is the sun, as its curved shape concentrates and focuses sunlight into a specific point or beam, enhancing brightness and energy concentration for applications like solar heating or lighting. The differences in the source's nature and light distribution necessitate the use of different mirror types for optimal performance.
Why are concave mirrors used in flood lights?
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.
A light beam striking a concave inward curve mirror reflects and?
converges towards a focal point if the light is emitted from the focal point or beyond it. If the light source is located between the mirror and the focal point, the reflected light diverges.
What happens to the rays falling parallel to the axis on a concave lens?
In a concave lens, the parallel rays of light diverge or spread out after passing through the lens. This causes them to appear to come from a point called the focal point on the same side of the lens as the light source.
