AI Thread Summary
The discussion centers on understanding the significance of the two primary rays in the context of reflection and refraction. Primary rays typically refer to light rays that travel directly from a source without being reflected or refracted. The lab involved testing concave and convex mirrors and lenses to observe how object distance from the focal point affects image formation. The key question is how these primary rays relate to the general rules governing reflection and refraction. Clarifying this relationship is essential for grasping the underlying principles of optics.

Homework Statement



Explain the significance of the two primary rays and what that means for the general rules for reflection(refraction)

Homework Equations



No equation for it.

The Attempt at a Solution


No attempt, still trying to figure out what primary rays(My guess is ultraviolet rays)

You will have to give us the entire problem. Primary ray usually refers to an unreflected or unrefracted ray - the light ray that comes directly from the source.

Thats the entire problem for it. We did a lab for concave and convex mirror and lens to find out if an object distance from a focal point changes the image. We had to write an abstract about it and one of the question he wanted to know is: Explain the significance of the two primary rays and what that means for the general rules for reflection(refraction).
 

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'

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...
