    I Phase Plane Diagram w/ Complex eigenvalues

    Im not quite sure if that means all solns would be approaching the center? Clockwise or Counterclockwise

    I Phase Plane Diagram w/ Complex eigenvalues

    Is the spiral I drew here clockwise or counterclockwise ? What’s a trick to know whether it’s going CCW or CW. Thanks!

    Optics Problem: What optical instrument does this?

    Im thinking that this is a telescope, but I am having a lot of trouble answering this question. If the plane waves arrive at different angles, wouldn't the image be distorted?Would the lenses possibly be spherical because of this?

    Hecht optics: Request for screenshot of this figure please

    Can someone simply screenshot this figure and send to me: Consider Figure 5.4 d) on page 153 of Hecht. As shown, converging rays that are headed toward the point F convert to a plane wave upon hitting the boundary between n2 and n1.

    Rayleigh Scattering: Blue/Red Irradiance Ratio & Distance

    Hi everyone, does the scattering irradiance ratio between blue/red change with distance with Rayleigh scattering? I would think that it would remain generally constant..

    Energy Method: Inclined Plane - Solving for Velocity and Time

    So far I've got E=1/2m(dx/dt)^2+mgh this can be rewritten as (dx/dt)^2=2(E-mgxsin(Θ))/m Would there not be a positive and negative solution? dx/dt=±sqrt(2(E-mgxsin(Θ))/m) or do we discard the negative one? Why would we do so, if that's the case. So far I've only solved the postive solution and...

    How do I modify plane waves to represent the EM field of a lightbulb?

    Thank you so much for your reply! Would I have to consider spherical waves in this problem? Or can I simply treat them as plane waves moving in the x direction (because of the conditions given in the problem). If I can treat it as a planar wave i would write an equation like: Ex=Eo(kx±⍵t) The...

    How do I modify plane waves to represent the EM field of a lightbulb?

    I don't know where to start for part (c), I've managed to get (a) and (b). Can someone simply guide me, I think I'm having trouble understanding what the teacher means by just having an x dependance... Does this mean I only work with the x components of the magnetic field and the electric...

    Complex representation of a wave

    Homework Statement: Hi there, I'm currently taking an Optics course and the teacher is expecting us to have an understanding of the complex representation of waves. Although, hardly any of us have even heard of this yet. I've tried to google how to convert a cos(obj) and sin(obj) to an...
