AI Thread Summary
The discussion centers on understanding specific equations related to wave physics. The equation k = 2(pi)/wavelength defines 'k' as the wave number, indicating the phase change per meter of a wave. The second equation, theta_p = tan^-1(n2/n1), relates to Brewster's angle, which is significant in understanding the polarization of electromagnetic waves. The third equation, dx/L = m(wavelength), involves variables d and x, which pertain to diffraction patterns in wave behavior. Overall, these equations are essential for analyzing wave properties and interactions.

hey, I am look over some equations given to me by my instructor, and I am reading the book and i cannot find what they do


k= 2(pi) / wavelength......what is k


and theta_p = tan^-1 (n2/n1) what is theta_p

and dx/L = m(wavelength) what is d and x what does this find...



thanks in advanced,,,,, great website

'k' is called the wave number i think. if you freeze a wave in time, k is equal to how much the phase changes per meter. you can tell by the units. 2pi is in radians and wavelength is in meters so k = radians/meter
 
First one is the wave number.

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.
