    2d Field
AI Thread Summary
The discussion centers on finding a 2D application where an electric field is scattered by a conductor. A parabolic antenna is mentioned as a suitable example, but the original poster seeks additional applications. One suggestion offered is the reflection of radio waves off the ionosphere, which is also considered a conductor. However, the original poster clarifies that the reflection must specifically involve a conductor. The conversation highlights the challenge of identifying suitable examples beyond the parabolic antenna.

hey, does anyone know an application in which an electric field is scattered by a conductor (2D). A parabolic antenna is a good example, but i need another one.

thanks, levi

How about the reflection of radio waves off the ionosphere?
 
no, the reflection has to be off a conductor
thanks anyway
 
The ionosphere is a conductor.
 
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}...
