    Experiment Slit
AI Thread Summary
Increasing or decreasing the width of the slits in the double slit experiment affects the interference pattern. A wider slit results in a decrease in fringe separation due to the relationship described by the formula sin(theta) = n*lambda/d, where d refers to slit separation, not width. The brightness of light fringes increases with wider slits, while dark fringes become less distinct. The discussion emphasizes that the width of the slits influences the intensity of the light rather than the fringe separation directly. Understanding these effects is crucial for analyzing the interference patterns produced in the experiment.

Homework Statement



q. when the width of both slits in double slit experiment is increased or decreased what happens to:
1. separation of fringes
2. brightness of light fringes
3. brightness of dark fringes

and why?

The Attempt at a Solution


couldnt think of any thing

Do you know the formula sin(theta)=n*lambda/d? You should be able to answer 2 and 3 just by thinking about what happens if the slit width is made very large.

i know the equation but it does not deal with the WIDTH of the slits instead it deals with the SLIT SEPERATION.
 

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...
