How can a rough value of the focal length of a concave mirror be obtained?
rough focal length of concave mirror
Why is concave lens called a negative lens?
Concave lens is called a negative lens because it has a negative 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 the focal length of concave mirror to form real image?
15cm
For very small angles the focal length of a concave mirror is?

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 normal laboratory concave lens?
A "normal" concave lens might have a focal length anywhere between a few mm and a couple of metres. Outside that range there is nothing particularly abnormal, perhaps just less common.
