What is the defect that all the concave spherical mirrors have?
All concave spherical mirrors have a defect known as spherical aberration, which causes light rays coming from a single point on the object to not converge at a single point after reflection, resulting in a blurred image.
Why concave and convex mirrors are called spherical mirrors?
Concave and convex mirrors are called spherical mirrors because their reflecting surfaces are part of a sphere. This means that if the mirror were extended to form a complete spherical shape, it would have the same radius of curvature for all points on its surface.
Do convex and concave mirrors obey the law of reflection?
Yes, both convex and concave mirrors obey the law of reflection, which states that the angle of incidence is equal to the angle of reflection. This law applies to all types of mirrors, ensuring that light rays reflect predictably off the mirror's surface.
Do all types of mirrors give rise to diffused reflection?
No, not all types of mirrors give rise to diffused reflection. Mirrors with smooth surfaces, such as plane or concave mirrors, produce specular reflection where the light rays are reflected at a consistent angle. Diffused reflection occurs with rough surfaces or materials that scatter light in various directions.
Which is better concave or convex?
It depends on the context. In terms of mirrors, a concave mirror is typically better for focusing light and forming images, while a convex mirror is better for a wider field of view and reflecting light in all directions.

What is the difference between parabolic and concave mirrors?
In the case of concave mirrors parallel rays, parallel to the principal axis and incident near the pole(axial rays), after reflection will converge to the principal focus.Rays reflected from the marginal portions of the mirror(marginal rays) will converge to points nearer than the focus. Due to this the image formed by a concave mirror of large aperture will be blurred. This defect is called spherical aberration. This defect can be overcome by using parabolic mirrors. In a parabolic mirror all the rays, axial rays as well as the marginal rays, incidenting on it after reflection will converge to the same principal focus. This is due to the geometric property of the parabola, that is parabola allows only one focus.Hence in a parabolic mirror there is no spherical aberration and the image will be sharp and clear.
What is the cause of the defect that exist in all single lenses?
defect that exist in all single lenses:1. Spherical aberration2. Chromatic aberration

Why are concave mirrors used in the head light of vehicles?
Concave mirrors are used because they will reflect a light source inside the curve in one general direction. To be more specific, the mirrors are close to parabolic. Parabolas have the property that light beams generated at the focal point of the parabola are all reflected parallel out of the mirror.
Which type of mirror is used by ENT doctors?
ENT doctors use a mirror called a "laryngeal mirror" to examine the throat, vocal cords, and other areas of the larynx. This mirror is specifically designed to provide a clear view of these areas during examinations or procedures. So, if you ever need a throat check-up, just remember, it's all about that laryngeal mirror, honey.
Do all types of mirrors give rise to diffused reflection?
No, not all types of mirrors give rise to diffused reflection. Mirrors with smooth surfaces, such as plane or concave mirrors, produce specular reflection where the light rays are reflected at a consistent angle. Diffused reflection occurs with rough surfaces or materials that scatter light in various directions.
When backing what is the best definition of the big piucture?
Visibility from all directions. This can best be achieved by looking in all directions before backing and then checking your mirrors on each side of the vehicle. Better view is obtained when using "spot" mirrors but one has to remember that images are closer than they appear in those smaller concave mirrors.
Which is better concave or convex?
It depends on the context. In terms of mirrors, a concave mirror is typically better for focusing light and forming images, while a convex mirror is better for a wider field of view and reflecting light in all directions.
Which type of telescope uses concave mirrors to increase the size of the image being viewed?
Refracting
What kind of curve mirror do you see in department store?
In department stores, you typically see concave mirrors, which curve inward. These mirrors are used to provide a wide-angle reflection to help customers see themselves from different angles while trying on clothes or accessories.
