Radius of Curvature of a 10cm Concave Mirror

AI Thread Summary
The focal length of a concave mirror is directly related to its radius of curvature, with the radius being double the focal length. For a concave mirror with a focal length of 10 cm, the radius of curvature is 20 cm. This relationship is fundamental in optics and can be easily found through a quick search. The discussion emphasizes the simplicity of the calculation involved. Understanding this concept is essential for working with concave mirrors in various applications.

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:

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
