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.
The focal point of a concave mirror is 5 cm what is its center of curvature?
10 cm from the mirror.
Will focal length of concave mirror change when kept in water?
yes
Focal length of a concave mirror?
1/object distance + 1/ image distance = 1/focal length
What determines whether a real or a vitual image is formed from a concave mirror?
A real image is formed by a concave mirror when the object is located beyond the focal point. A virtual image is formed when the object is located between the mirror and the focal point.
Does a concave mirror have a focal point?
Yes, a concave mirror has a focal point. Light rays parallel to the mirror's axis converge at the focal point after reflecting off the mirror.
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 are the properties of an image seen in a concave mirror if the object is closer to the mirror than the focal point?
If the object is closer to the concave mirror than its focal point, the image will be virtual, upright, and larger than the object. It will also be located behind the mirror.
How You place a flower 18 feet from a concave mirror. The mirror generates a virtual image of the flower that appears to be behind the mirror. What can you infer about the focal point of the mirror?
Since the image is virtual and appears behind the mirror, the focal point of the concave mirror is also located behind the mirror. This indicates that the focal point is a positive value, based on the mirror's characteristics.
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.
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 image in a concave mirror when an object is closer to the mirror than one focal length?
When an object is placed closer to a concave mirror than its focal length, the image formed is virtual, upright, and magnified. The image is located behind the mirror, and the rays of light appear to diverge from a point behind the mirror rather than converging at a real focal point.
What are the properties of images seen in a concave mirror if the object is from the mirror than the focal point?
the image will always be located somewhere on the opposite side of the mirror.
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.
Why a side mirror is never a concave mirror?
A concave mirror would focus the light back towards the focal point of the mirror. You would not be able to use the mirror effectively with a concave.
Where should the object be placed in order to produce a larger object behind a concave mirror?
The object should be placed beyond the focal point of the concave mirror. This will produce a larger, magnified image located behind the mirror. By positioning the object past the focal point, the reflected rays will converge to form an image that is larger compared to the object.
