Question

image formed by concave mirror?? Related:  Magnification and Power of a Lens?

Answer

Answer

Image Formation By Concave Mirror

By changing the position of the object from the concave mirror, different types of images can be formed. Different types of images are formed when the object is placed:

At the infinity
Beyond the centre of curvature
At the centre of curvature
Between the centre of curvature and principal focus
At the principal focus
Between the principal focus and pole.

When an object is placed behind thecenter of curvature, a real image isformed between the center of curvature and focus. The size of theimage is smaller as compared to that of the object.

Answer

Image formed by Concave Mirror:
A concave mirror is a spherical mirror that curves inward, like the inside of a spoon. The image formed by a concave mirror can be real or virtual, depending on the position of the object relative to the focal point of the mirror. When the object is placed beyond the focal point, a real and inverted image is formed. When the object is placed between the focal point and the mirror, a virtual and upright image is formed.

Magnification:
Magnification is the ratio of the size of the image to the size of the object. It is denoted by the letter 'm'. Magnification can be calculated using the formula: m = height of image / height of object. A magnification greater than 1 indicates that the image is larger than the object, while a magnification less than 1 indicates that the image is smaller than the object.

Power of a Lens:
The power of a lens is a measure of the ability of the lens to bend light rays. It is denoted by the letter 'P' and is measured in diopters (D). The power of a lens can be calculated using the formula: P = 1 / focal length. A lens with a higher power has a shorter focal length and bends light rays more strongly than a lens with a lower power.

In summary, a concave mirror can form a real or virtual image depending on the position of the object relative to the focal point. Magnification is the ratio of the size of the image to the size of the object, while the power of a lens is a measure of its ability to bend light rays.
