The objects size is not going to change. The image size, however, would.

Will focal length of concave mirror change when kept in water?
yes
The distance between a mirror and its focal point is called the?
Focal length, positive number with a concave mirror, negative for a convex mirror.
If the surface of a concave mirror is made more curved what happens to its focal length?
A concave mirror is a spherical mirror with a reflective inside surface. When the reflective surface is made more curved, the distance between the focal point and the surface increases. A concave mirror can form both virtual or real images.
Focal length of a concave mirror?
1/object distance + 1/ image distance = 1/focal length
Why the focal length of concave mirror changes in water?
I don't think so. The focal length would remain the same. It mainly depends on the radius of curvature of the mirror.
Will focal length of concave mirror change when kept in water?
yes
How can a rough value of the focal length of a concave mirror be obtained?
rough focal length of concave mirror
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.
Why does the focal length of a concave mirror not change when held in water?
The focal length of a concave mirror is a function of its radius only (a geometry function), not of its material nor the material surrounding it. To change the focal length you wound have to alter it physically. Keep in mind that the light or whatever is being focused does not make a media change. It never enters the mirror media. It is always in the surround media, whatever that is, so Snell's law does not apply here.
What is the focal length of concave mirror to form real image?
15cm
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 do we use concave mirror as converging mirror
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.
The distance between a mirror and its focal point is called the?
Focal length, positive number with a concave mirror, negative for a convex 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
For very small angles the focal length of a concave mirror is?
Half of the radius
What will happen to the focal length of a concave mirror or a convex mirror when the incident violet light on them is replaced by red light?
Nothing. The focal length is defined as point where all of the light converges after passing through the lens ( for a convex mirror)and only depends on the mirror's curvature. So changing the incident light ray will cause no change in the focal length of the mirror.
