What is the magnification of a 4 cm tall object placed 40 cm from a concave mirror having a focal length of 10 cm?
The magnification can be calculated using the magnification formula: M = -f / (f - d), where f is the focal length and d is the object distance. In this case, f = 10 cm and d = 40 cm. Plugging in these values gives M = -10 / (10 - 40) = -10 / -30 = 1/3. Therefore, the magnification is 1/3.

How do you calculate image position when given magnification of ian image by a concave miarror?
To calculate the image position when given magnification by a concave mirror, you can use the mirror equation: 1/f = 1/d_o + 1/d_i, where f is the focal length of the mirror, d_o is the object distance, and d_i is the image distance. Magnification, M, is also given by -d_i/d_o. By substituting the values of magnification and focal length into the mirror equation, you can solve for the image distance and then determine the image position.
What is the Magnification equation for concave mirror?
The magnification equation for a concave mirror is given by the formula: M = - (image distance) / (object distance), where M is the magnification, image distance is the distance from the mirror to the image, and object distance is the distance from the mirror to the object. Negative magnification indicates an inverted image.
What is the focal length of concave mirror of radius 20cm?
The focal length of a concave mirror is half of its radius of curvature. Therefore, for a concave mirror with a radius of 20 cm, the focal length would be 10 cm.
What is the relationship between the radius of curvature and focal length in a concave mirror?
In a concave mirror, the radius of curvature is twice the focal length.
What will the image produced by a concave mirror be?
A concave mirror can produce a real or virtual image, depending on the location of the object. Real images are formed in front of the mirror and can be projected onto a screen, while virtual images are formed behind the mirror and cannot be projected. The characteristics of the image, such as magnification and orientation, are determined by the mirror's focal length and the object's distance from it.

How can a rough value of the focal length of a concave mirror be obtained?
One way to estimate the focal length of a concave mirror is to use the mirror formula: 1/f = 1/do + 1/di, where f is the focal length, do is the object distance, and di is the image distance. By measuring the object distance and the corresponding image distance, you can calculate an approximate value for the focal length of the concave mirror.
WHAT HAPPENS TO THE FOCAL LENGTH OF A CONCAVE MIRROR AS THE CURVATURE OF THE MIRROR IS INCREASED?
As the curvature of a concave mirror is increased, the focal length decreases. This means that the mirror will converge light rays to a focal point at a shorter distance from the mirror. The mirror will have a stronger focusing ability.
Why do images in a concave mirror appear inverted?
If an object's distance from the concave mirror is greater than the mirror's focal length, then the mirror image of it will be inverted. If the distance from the concave mirror is less than the focal length of the mirror, the image will not be inverted. No image will be produced if the distance from the mirror to the object is equal to the mirror's focal length.
An object is placed between focus and centre of curvature of a concave mirror. Draw a ray diagram and derive mirror formula. Also write magnification formula.?
In a concave mirror, when an object is placed between the focus and the center of curvature, the image formed is real, inverted, and enlarged. To derive the mirror formula, use the mirror formula: 1/f = 1/v + 1/u, where f is the focal length, v is the image distance, and u is the object distance. The magnification formula is: M = -v/u, where M is the magnification, v is the image distance, and u is the object distance.
Describe an image formed by concave mirror when an object is less than one focal length from the mirror?
This is for a concave spherical mirror. This depends on if the image is insed or outside the foacl point of the lens. If the image is outside the foacl point of the lense it is then inverted (upside down), smaller in magnification, and is a real image which means the rays converge to create a real image that can be projected. If the object is inside the foacl point of the lens then the image has a negative image distance (through the mirror), is upright, is larger (magnification), and is a virtual image constructed from diverging light rays and cannot be projected.
When you look really closely into a concave mirror your image is magnified what happens when you move your face away?
When you move your face away from a concave mirror, the image you see in the mirror will become smaller and eventually disappear as you move further away from the focal point of the mirror. This is because the magnification effect of the concave mirror is strongest when objects are close to the mirror's focal point.
Image form by concave mirror?
A2. A concave mirror is commonly used as a make-up mirror or a shaving mirror. For at close distances, (well inside it focal length) it gives a modest magnification. At distances greater than its focal length, it gives diminished images.
