Radius of Curvature of a 10cm Concave Mirror

In summary, the radius of curvature of a concave mirror is the distance between the center of the mirror and its focal point. For a 10cm concave mirror, the radius of curvature is equal to 5cm. It can be calculated using the formula R=2f, where R is the radius of curvature and f is the focal length of the mirror. The radius of curvature is important because it affects the size, position, magnification, and clarity of the image formed by the mirror. The radius of curvature of a concave mirror can be changed by altering the shape or position of the mirror. It is also different from the radius of curvature of a convex mirror, which is equal to twice the focal length.

Google the words... concave mirror focal length radius of curvature

Just by reading the text below the first link you should be able to find the answer. I'll give you a hint, all you need to do is multiply your 10 cm by a single number!

oh ok so it's just the double of the focal length then? thanks so much:biggrin:
 

1. What is the radius of curvature of a 10cm concave mirror?

The radius of curvature of a concave mirror is the distance between the center of the mirror and its focal point. For a 10cm concave mirror, the radius of curvature is equal to 5cm.

2. How is the radius of curvature of a concave mirror calculated?

The radius of curvature can be calculated by using the formula R=2f, where R is the radius of curvature and f is the focal length of the mirror. For a 10cm concave mirror, the focal length is 5cm, so the radius of curvature would be 10cm.

3. What is the significance of the radius of curvature in a concave mirror?

The radius of curvature is important because it determines the strength and properties of the concave mirror. It affects the size and position of the image formed by the mirror, as well as the magnification and clarity of the reflected image.

4. Can the radius of curvature of a concave mirror be changed?

Yes, the radius of curvature of a concave mirror can be changed by altering the shape or position of the mirror. By adjusting the position of the mirror, the focal length and radius of curvature can be changed, which in turn affects the properties of the reflected image.

5. How does the radius of curvature of a concave mirror compare to that of a convex mirror?

The radius of curvature of a concave mirror is equal to half of the focal length, while the radius of curvature of a convex mirror is equal to twice the focal length. This means that a concave mirror has a shorter radius of curvature than a convex mirror, resulting in a stronger curvature and different properties of the reflected image.
