AI Thread Summary
The discussion focuses on calculating the interference and diffraction pattern created by two slits for light with a wavelength of 600 nm, positioned 2.0 m from a wall. Key equations include d sin(theta) = mλ and a sin(theta) = mλ, with the ratio of slit separation to width given as d/a = 5. The user has identified that the dark spot is located 0.0045 m from the center point and seeks assistance in solving for theta. The conversation highlights the importance of visual aids in understanding the problem, as one participant notes the challenge of not having access to the referenced figure. The thread emphasizes the application of mathematical relationships in determining the parameters of the interference pattern.

Homework Statement



interference/diffraction pattern formed by two slits for light with λ=600nm on a wall L=2.0m from the slits. find a (width) and d (separtation of slits.

Homework Equations



looking at the figure given d/a=5
dsin(theta)=mλ
asin(theta)=mλ

The Attempt at a Solution



so dsin(theta)=5(lambda) and asin(theta)=1λ
also looking at the figure the dark spot appears .0045m from the center point.
How do I solve for theta?

Unfortunately we don't have the luxury of being able to "look at the figure given".
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
