In thinking of an inductor as a circuit element, it is helpful to consider its limiting behavior at high and low frequencies. At

one extreme, the inductor might behave like a short circuit, that is, like a resistor with almost no resistance (an ideal wire) having essentially no voltage drop across it no matter what the current. Alternatively, the inductor might behave like an open circuit, that is, like a resistor with large resistance so that essentially no current will flow no matter what the applied voltage. Based on the formula you obtained for the reactance, how does an inductor behave at high and low frequencies?
A) like a short circuit at both high frequencies and low frequenciesB) like an open circuit at both high frequencies and low frequenciesC) like an open circuit at high frequencies and a short circuit at low frequenciesD) like an open circuit at low frequencies and a short circuit at high frequencies

Answer:

Lyrics C :like an open circuit at high frequencies and a short circuit at low frequencies

Explanation:

The impedance produce by the presence of an inductance in an electric circuit  has a general equation  Z(r) = jωl  where  j is the imaginay number, l is the inductor in henrios and ω is the frecuency of the curent ( ω = 2πf , f is the frecuency in hertz)

So module of the inductance directly depends on  ω = 2πf   then when f the frecuency increase, the value of ωl, also increase and when the value of f decrease ωl will decrease. For very high value of ω the inductance can become very very high ( even up to an open circuit ) and the              opposite for very low values of frecuencies ωl could be very low (as to a short circuit

Estimate how far apart the rays of deepest red and deepest violet light are as they exit the bottom surface. assume nred = 1.57
Harlamova29_29 [7]
We begin by noting that the angle of incidence is the one that's taken with respect to the normal to the surface in question. In this case the angle of incidence is 30. The material is Flint Glass according to the original question. The refractive indez of air n1=1, the refractive index of red in flint glass is nred=1.57, finally for violet in the glass medium is nviolet=1.60. Snell's Law dictates:
n_1sin(\theta_1)=n_2sin(\theta_2)
Where \theta_2 differs for each wavelenght, that means violet and red will have different refractive indices in the glass.
In the second figure provided details are given on which are the angles in question, \Delta x is the distance between both rays.
\theta_{2red}=Asin(\frac{sin(30)}{1.57})\approx 18.5705
\theta_{2violet}=Asin(\frac{sin(30)}{1.60})\approx 18.21
At what distance d from the incidence normal will the beams land at the bottom?
For violet we have:
d_{violet}=h.tan(\theta_{2violet})\approx 0.0132m
For red we have:
d_{red}=h.tan(\theta_{2red})\approx 0.0134m
We finally have:
\Delta x=d_{red}-d_{violet}\approx2.8\times10^{-4}m
