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.

What is concave mirror?
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.
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 a concave mirror affect light?
A concave mirror will tend to "focus" light to some degree, depending on the curvature of the mirror. A parabolic mirror will bring reflected light to a sharp focus, and telescopes use this type of curve for the shape of their reflective surface. And for exactly the reasons you think they do.

What is a concave mirror?
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.
Why inner curved surface is known as Concave mirror?
Inner curved surface is known as concave mirror because inner side of the spherical mirror is polished to reflect the light is called concave mirror,and concave mirror is know because concave mirror converges parallel beam of light.
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.
Can a concave mirror act as a convex mirror?
No, a concave mirror and a convex mirror have different curvatures and focal points. A concave mirror reflects light inward, converging it to a focal point, while a convex mirror reflects light outward, diverging it. They cannot interchange their functions.

Describe what happen to parallel light rays hitting in a concave mirror?
Parallel light rays hitting a concave mirror will converge to a single focal point after reflection, due to the mirror's inward or converging shape. The focal point is located on the principal axis of the mirror, halfway between the mirror's center and the vertex. This property of concave mirrors is used in applications like focusing light in telescopes and for creating images in reflective devices.
When the surface of a mirror curves like the inside of a bowl it is called a?
concave mirror
What happens when a source of light is placedat the focal point of a concave mirror?
When a source of light is placed at the focal point of a concave mirror, the light rays will be reflected parallel to the principal axis. This is because in this position, the light rays are reflected back on themselves, resulting in parallel rays.
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 a concave mirror work?
A concave mirror is a spherical mirror which is curved inward, where the inside surface is reflective. They work by reflecting the light captured into the centre of the mirror, creating a focal point in the centre of the mirror.
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.

What is it called when a mirror with a surface that curves inward like the inside of a bowl?
It is called a concave mirror. Concave mirrors curve inward and have reflective surfaces that cave inwards. They can be used to focus light to create real or virtual images.
