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.
How can a rough value of the focal length of a concave mirror be obtained?
rough focal length of concave mirror
What is the Magnification equation for concave mirror?
-di/do-p/qhi/ho
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.
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.

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.

What is the best mirror for magnification so I can clean my pores?
you can get concave mirrors especially from school's science equipments suppliers.
What is the focal length of concave mirror to form real image?
15cm
Will focal length of concave mirror change when kept in water?
yes
Why and why concave mirrors are not suitable for makeup?
Concave mirrors bring the image to a focal point. Convex mirrors produce a diverging image - the further away from the mirror you are - the larger the magnification.
Is concave mirror in shape of parabola?
no concave mirror is in shape of concave mirror
Why do we use concave mirror as converging mirror?

Why concave mirror is used for shaving?
Some people use concave mirror because when a man stands between the principal focus and pole of a concave mirror,he sees an enlarged,erect and virtual image of his face.this is the reason why a concave mirror of large focal length is used for shaving. concave mirrors concentrate on one focus and while shaving it concentrate on a point and the image is enlarge which prevents the face from cutting. because when a man stands between the pricipal focus and pole of a concave mirror , he sees enlarged ,erect and virtual image of his face .that is why concave mirror of large focal length is used for shaving
