Convex Lens Image: Solve Problem & Describe Image

AI Thread Summary
The discussion focuses on solving a problem related to locating an image formed by a convex lens. Participants emphasize the need to use ray diagrams to determine the image's characteristics, including whether it is real or virtual, upright or inverted, and its size relative to the object. The consensus is that the image is real, inverted, and larger than the object, with a magnification greater than one. Additionally, the importance of calculating the focal length and using optics resources for reference is highlighted. The thread concludes with a clear identification of the image properties based on the provided diagrams.

I have to complete a problem about locating an image for a convex lens but I'm having trouble with it. I tried it out, but I can't complete it. Can someone help please?

Locate the image for the convex lens below. Use any two rays to do so. Give the characteristics of the image.

I'm having trouble particularly with describing the image. I'll attach the picture of the lens and my answer to it.

you need to work out the focal length of the lense, try looking in an optics book.
 
Is the image real or virtual? Is it upright or inverted? How much larger is it than the object?

No, it's a graphical problem. The first diagram shows the focal points and the location of the object, so he has enough information to locate the image, which he did in the second diagram.

All he has to do now is describe the key characteristics of the image. Usually this means saying whether it's real or virtual; upright or inverted; enlarged or reduced in size. Maybe calculate the numerical value of the magnification by measuring the sizes of the object and image.
 
okay, thanks a lot guys.

So it's real, inverted, and M>1
 

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

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...
