General Lens Question: Diverging or Converging

AI Thread Summary
The discussion centers on determining whether a meniscus lens is converging or diverging based on curvature. It is clarified that if the curvature of the first lens is greater, the lens will converge, while a greater curvature in the second lens results in divergence. Additionally, the thickness of the lens plays a role: a thicker middle indicates convergence, whereas a thinner middle suggests divergence. This understanding helps in identifying the optical behavior of the lens. The key takeaway is that curvature and thickness are critical factors in lens classification.

Homework Statement



General question here: If I have a lens that looks like two concave lenses put together (I believe it is called a Meniscus), how do I conceptually tell whether the lens should be converging or diverging? I think I remember reading something saying that it depends upon which lens has the greater Curvature but I can't find where I saw this...
Any help would be greatly appreciated! Thanks!

Never mind: figured it out. If the curvature of the first lens is greater, then it is converging. If the curvature of the second lens is greater, it is diverging.
 
If the lens is thicker in the middle, it's converging; if thinner, diverging.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
