Angle Maxima and nodes and antinodes

AI Thread Summary
The discussion revolves around understanding nodes and antinodes in the context of wave interference. The original poster attempts to solve a problem using the equation dsin(θ) = λm, calculating angles for specific orders of maxima. They seek clarification on how to visually represent nodes and antinodes, referencing a diagram from their textbook. A response suggests replacing wavy lines with straight lines to illustrate path differences more clearly. The conversation emphasizes the relationship between path differences and the formation of nodes and antinodes in wave patterns.

Homework Equations



dsin(\theta) = \lambdam

The Attempt at a Solution



(0.00003m)(sin(\theta)) = (0.000000550m)(2) ------------> 2.10o
(0.00003m)(sin(\theta)) = (0.000000550m)(3) ------------> 3.15o


I looked through my textbook, but the only piece that I could find about nodes/anti-nodes was the diagram that I attached. Can someone explain how I draw them/what they are?

THANKS SO MUCH!

Thanks!
But how would I show how the nodes and anti-nodes are created?
 
for wavelength λ, it's an anti-node if the path difference is … ? :smile:
 

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...
