T/F: When light passes through two or more narrow slits, an alternating dark and bright pattern is observed on a screen because of reflection of light. T/F: Optical fibers work because of total internal reflection of light. T/F: You see colors in a rainbow because of interference of light. T/F: A light ray bends when it goes from one medium to another because of refraction. T/F: When you look into a pool of water, the depth looks less than it...

5. [5 pts] Deconvolution. A signal x passes through a channel (which is a convolution system) to produce the signal y, i.e., y- hx. The impulse response of the channel is h(t) = te-tu(t). This means that y is a kind of 'smeared' or 'averaged' version of x. Here's the question: is it possible to reconstruct the signal x knowing only the signal y? This process of undoing the effect of convolution is called deconvolution. As you can imagine, deconvolution...

Pre-Laboratory Work 3 (estimated time 1 hour) In reality, when a circuit is first connected to a power source the current through the circuit does not jump discontinuously from zero to its maximum value. Instead, the current increases smoothly due to the effect known as self-induction. The circuit itself can be seen as a current loop and as the current increases with time, the magnetic fields circling the wires become stronger. Thus, the magnetic flux through the loop itself increases,...

1. Fill out the following table by indicating which general technique (light microscopy (LM) or electron microscopy (EM]) could be used to observe each structure or phenomenon. Put "no" in the box if the technique could not be used. If light microscopy can be used, name one technique (bright-field, phase-contrast, fluorescence, etc.) that you think would be effective. You will find some useful information in Appendix 1 of this manual and Chapter 18 of your textbook. Structure or phenomenon Could...

Pumping from a Standing Position The pumped swing is modeled as a pendulum with variable length L. The rider is modeled as a point mass m, and L is the distance from the rider's center of mass to the fixed swing support point O. Conservation of angular momentum for a point mass undergoing plane motion is where H is the angular momentum of the body...
