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.
Focal length of a concave mirror?
1/object distance + 1/ image distance = 1/focal length
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.
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
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.
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.
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.
What is the focal length of concave mirror to form real image?
The focal length of a concave mirror to form a real image is positive. It is equal to half the radius of curvature (R) of the mirror, and the image is formed between the focal point and the mirror.
How do you find focal length of concave mirror?
The focal length of a concave mirror can be found by using the mirror formula, which is 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 and image distances from the mirror, you can calculate the focal length using this formula.
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
What is the image formed by F and 2F in concave mirror?
The image formed by a concave mirror at the focal point (F) will be at infinity and will be highly diminished. The image formed by a concave mirror at twice the focal length (2F) will be inverted, real, and diminished.
