Young's Double Slit Homework: True/False?

AI Thread Summary
In the discussion about Young's Double Slit experiment, the initial homework statement presents various claims regarding the light pattern on a screen behind the slits. The correct assessment is that only the statement about dark lines appearing due to destructive interference is true, while the others are false. Participants emphasize the importance of understanding double slit interference and suggest reviewing textbook materials for clarity. The confusion stems from misinterpretation of the interference pattern, which typically includes both bright and dark regions. Ultimately, the correct conclusion is that only statement three is accurate.

Homework Statement


A double slit is illuminated by a light source. Which of the following are true about the image projected on the screen behind the slits?


Homework Equations


1. A solid band of light will appear on the screen because constructive interference occurs everywhere.
2. The screen will be dark because constructive interference cannot occur anywhere.
3. Dark lines will appear at points where there is destructive interference.
4. A single bright line will appear on the screen.
5. only two bright lines will appear on the screen

1 is true. rest are false.

am i correct? Can someone please help me? thanks!

No, I don't think you're understanding double slit interference. Reread the relevant parts of your textbook; unless your textbook is really bad, I'm sure there will be a picture of the interference pattern.
 
Thanks, I was actually able to figure it out. Only 3 is true.

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.
