50 Important One-Liners on Concave and Convex Mirrors
- A concave mirror curves inward, resembling the inside of a spoon.
- A convex mirror curves outward, like the back of a spoon.
- Concave mirrors can form real or virtual images, depending on object position.
- Convex mirrors always produce virtual, upright, and diminished images.
- The focal point of a concave mirror is where parallel rays converge after reflection.
- Convex mirrors have a virtual focal point behind the mirror.
- The focal length of a concave mirror is positive in the sign convention.
- The focal length of a convex mirror is negative in the sign convention.
- Concave mirrors are used in reflecting telescopes to focus light.
- Convex mirrors are used in vehicle side mirrors for a wider field of view.
- The image formed by a concave mirror is real when the object is beyond the focal point.
- A convex mirror’s image is always located behind the mirror.
- The center of curvature of a concave mirror is twice the focal length.
- Convex mirrors have a center of curvature behind the mirror.
- Concave mirrors can produce magnified images when the object is between the focus and the mirror.
- Convex mirrors never produce magnified images.
- The mirror formula, 1/f = 1/u + 1/v, applies to both concave and convex mirrors.
- In the mirror formula, ‘f’ is the focal length, ‘u’ is the object distance, and ‘v’ is the image distance.
- Concave mirrors are used in makeup mirrors for magnified images.
- Convex mirrors are used in security mirrors at road intersections.
- The magnification of a concave mirror can be greater than, less than, or equal to one.
- The magnification of a convex mirror is always less than one.
- Concave mirrors form inverted images when the object is outside the focal point.
- Convex mirrors always form upright images.
- The principal axis is the line passing through the center of curvature and the mirror’s pole.
- The pole of a mirror is the point where the principal axis meets the mirror’s surface.
- Concave mirrors are converging mirrors due to their light-focusing ability.
- Convex mirrors are diverging mirrors as they spread out light rays.
- The image in a concave mirror is virtual when the object is inside the focal point.
- Convex mirrors are ideal for wide-angle surveillance due to their divergent nature.
- The radius of curvature (R) is related to focal length (f) by R = 2f.
- Concave mirrors are used in headlights to produce a parallel beam of light.
- Convex mirrors provide safety in ATMs and parking lots by reducing blind spots.
- The image distance in a convex mirror is always negative in the sign convention.
- A concave mirror can form an image at infinity when the object is at the focal point.
- Convex mirrors cannot form images at infinity.
- The size of the image in a concave mirror depends on the object’s position relative to the focal point.
- Convex mirrors produce images that are smaller than the object.
- Concave mirrors are used in solar concentrators to focus sunlight.
- Convex mirrors are used in shop security to monitor large areas.
- The image in a concave mirror is upright when the object is between the pole and the focal point.
- Convex mirrors have a wider field of view than concave mirrors.
- The sign convention for mirrors assigns positive values to real images and negative to virtual ones.
- Concave mirrors can form images that are either enlarged or diminished.
- Convex mirrors are not used for focusing light rays.
- The image formed by a convex mirror is always located between the pole and the focal point.
- Concave mirrors are used in dental mirrors to see magnified images of teeth.
- The magnification formula for mirrors is m = -v/u, where m is magnification.
- Convex mirrors reduce the risk of collisions by providing visibility around corners.
- Concave and convex mirrors are spherical mirrors with distinct reflective properties.
