Double Slits experiment central fringe intensity

AI Thread Summary
In a double slits experiment, widening each slit by two times is believed to double the intensity at the central fringe, resulting in an intensity of 2I. The reasoning behind this is that increasing the slit width allows more light to pass through, thereby increasing the intensity. The relationship between slit width and central fringe intensity suggests that greater slit width correlates with higher light intensity. This concept is fundamental in understanding the behavior of light in interference patterns. Overall, the discussion emphasizes the direct impact of slit width on intensity in the double slits experiment.

Homework Statement


In a double slits experiment, the intensity at the central fringe is I. What will be the intensity at the central fringe when each slit is widened 2 times?


Homework Equations





The Attempt at a Solution



My suggestion is that the intensity will be 2I...

But what is the reasoning?
What is the relationship between the central fringe intensity and the slit width?
 
I think that when the width of the each slit is doubled then the amount of light passing through will be double as well as the intensity

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}...

Thread 'Egg Drop Challenge! Need ideas for winning designs'

I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
