What is better a bigger or a smaller convex mirror Why?
A convex mirror bends light as it reflects the light, and the farther away a point is from the center, the more the light is bent. Because the image is smaller, more image can fit onto the mirror, so a convex mirror provides for a larger field of view than a plane mirror. This is why they are useful.
Why aperture is smaller than radius of curvature?
Why do we use spherical mirrors whose aperture is much smaller than its radius of curvature? We use spherical mirrors whose aperture is much smaller than its radius of curvature because spherical mirrors do not focus parallel light rays to a single focal point.
Does a convex mirror make things bigger or smaller?
Convex mirrors, or also called curved mirrors to make the object look shorter and wider than it really is. The image is smaller than the object projected, but it gets larger as it approaches the mirror. The images formed by a convex mirror cannot be projected onto a screen.
What happens if aperture is greater than radius of curvature?
Whats getting to happen if the aperture of the spherical class 10 physics CBSE. Vedantu MEGA Scholarship Admission Test is LIVE!
Does Convex make things look bigger?
A convex lens makes objects look larger and farther away. A concave lens makes objects look smaller and closer.
Why is a convex mirror called a diverging mirror?
A convex mirror is sometimes referred to as a diverging mirror due to the fact that incident light originating from the same point and will reflect off the mirror surface and diverge. After reflection, the light rays diverge; subsequently they will never intersect on the object side of the mirror.
Why the mirror equation is valid only if the aperture of the mirror is small?
Answer: Mirror formula is valid for reflection phenomena taking place on the surface of any mirror, and is not limited only to a small aperture.
What is the difference between aperture and radius of curvature?
Curvature means the curve like shape of a surface. Aperture is a whole or an opening through which light travels.
Does convex mirror make things look bigger?
If the mirror is bulged outward, it is known as a convex mirror. Convex mirrors make the object look shorter and wider than it really is. If the mirror is bent inward, it is a concave mirror. This type of mirror makes the object look taller and wider than it really is.
What is the relation between aperture and radius of curvature?
The relation between focal length (f) and radius of curvature (R) of a spherical mirror is that the focal length is equal to half of the radius of curvature i.e. f=R2.
What does a convex mirror reflect?
A convex mirror or diverging mirror is a curved mirror in which the reflective surface bulges towards the light source. Convex mirrors reflect light outwards, therefore they are not used to focus light.
Does convex mirror magnify?
NO!! CONVEX MIRROR CANNOT FORM MAGNIFIED IMAGE .. A CONVEX LENS CONVERGE THE RAYS GIVING YOU A SMALLLER IMAGE .
What is the radius of curvature of a concave mirror?
Solution: The radius of curvature of the mirror = 30 cm Thus, the focal length of the mirror = = 15 cm Example 4: An object is placed at a distance of 15 cm from a concave mirror of focal length 10 cm. Find the position of the image.
What is the focal length of a convex mirror?
A convex mirror has a focal length of -10.8 cm. An object is placed 32.7 cm from the mirror’s surface. Determine the image distance.
How is Focal Length related to Radius of Curvature? Definition : The equation relating the object distance (u) the image distance (v) and the mirror focal length (f) is called the mirror formula. The mirror has a small aperture. The object lies close to principal axis of the mirror.
Why is the aperture smaller than the radius of the mirror?
The point of using an aperture much smaller that the radius of the mirror is to restrict the incoming light to a region where rays do (almost) come to a single focal point. Thanks for contributing an answer to Physics Stack Exchange! Please be sure to answer the question.
