AI Thread Summary
When projecting a slide with the letter "p" using a slide projector, the image formed on the screen will be inverted, resulting in the letter appearing as "d." The discussion clarifies that slide projectors create real images that are displayed on screens, as opposed to virtual images, which cannot be shown on a screen. It emphasizes that virtual images are perceived as coming from a point where light does not actually converge, making them invisible on a physical surface. The participants agree that to see an image on a screen, it must be real and can be either upright or inverted depending on the setup. Understanding the nature of the image is crucial for effective projection.

Homework Statement


You wish to project a slide on a screen. One of the letters on the slide is a p. When you place the slide in the projector, how much the letter look when you insert the slide(as seen from behind the projector)? Explain.

a) p
b) d
c) b
d) q

Homework Equations


How converging (convex) and Diverging (concave) lenses work.

The Attempt at a Solution


EDIT: I believe the answer is all letters will be the same because slide projectors produce images that are the same size, virtual and upright. Could someone tell me if I'm right or wrong? Thanks.

A slide projector projects images that are formed on some kind of screen. Can you form a virtual image on a screen?

I do believe virtual images can be shown on a screen, but I think the image would be real, because the light comes together or something like that?
 
A virtual image cannot be formed on a screen. In a virtual image, the light seems as if if comes from a certain point. The image is at this point. Since the light isn't actually there, a screen placed there will not show an image.

So what type of image do you want to form in order for it to appear on a screen and will it be upright or upside down?
 
Thanks, I got it!
 
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'
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'
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...
