Inteference of light waves distance of double&single slit

AI Thread Summary
The discussion centers on the relationship between the distance of a single slit and a double slit in light wave interference patterns. It highlights that bringing the single slit closer to the double slit increases the intensity of light, resulting in brighter fringes in the interference pattern. Participants express confusion over the textbook's wording and seek clarification on the explanation. There is also a request for the textbook's name and whether it includes a diagram to better illustrate the concept. Understanding the physics behind light wave interference is essential for grasping these principles.

Homework Statement



in my textbook, it states that if the single slit together with the light source more closer to the double slit, the intensity of light form double slit increases . hence, the bright fringes of the inteference pattern would be brighter...i couldn't understand why . Can someone explain on this?

Well, I don't understand either. Perhaps the wording got distorted. Could you please rad what you typed and correct the errors ? Otherwise: What textbook might that be ? Does it also provide a drawing of the situation ?
 

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...
