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.
What is the relation between focal length and center of curvature?
The focal length of a concave mirror is about equal to half of its radius of curvature.
What is the Focal length of a concave mirror?
It is the point , on the central axis, where light, that is parallel to the central axis, passes thru after it is reflected from the mirror. It is also at a distance from the mirror equal to twice the radius of curvature of the mirror.
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.
What is the distance between a lens and its focal point is called?
This is called focal length.
What is the relationship between object distance image distance and focal length of concave mirror?
Sum of reciprocal of object distance and reciprocal of image distance gives the reciprocal of focal length
What is the relationship between object distance image distance and focal length of a concave mirror?
Sum of reciprocal of object distance and reciprocal of image distance gives the reciprocal of focal length
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 distance between mirror or lens and place where light rays meet?
Focal point
Focal length of a concave mirror?
1/object distance + 1/ image distance = 1/focal length
Which term defines the distance from the focal point to either a lens or a mirror?
focal length
Would the mirror equation work for plane mirrors?
No, it will not, this is because a plane mirror has no focal point. It's rays never converge at a single point like a concave mirror, and therefore it has no focal point The mirror equation is 1/f=1/di + 1/do, where f is the focal point, di is the distance of the image from the mirror, and do is the distance of the reflected object from the mirror. Since focal point is required for the equation, it can't work. Hope this helps.
The distance from lens to focal point is called?
It is called the 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.
The relation between focal length and radius of curvature of spherical mirror is?
The focal length of a convex mirror is half of its radius of curvature.
Estimate the focal length of a typical magnifying mirror that you might purchase from a drugstore?
Reflect the sun's light with the mirror onto some kind of target. Find the distance where the dot of light is smallest. That distance is the focal length.
