1) A laser produces a Gaussian beam with a waist immediately outside the laser, with a beam radius of 5 mm, an average power of 1 Watt, and a wavelength of 1 шт. We wish to choose a lens that will focus this beam as tightly as possible, subject to the constraint that the depth of focus must be at least 1 mm. a) What focal length lens should we choose? (Assume an ideal thin lens with no aberrations.) b)What...

1. (3 points) Consider a beam of light of wavelength 514.5 nm emitted by a laser. The diameter of the beam is 2.00 mm and there are 1.30 X 1018 photons emitted per second. a) Find the peak electric field for the electromagnetic wave that constitutes the beam. b) Find the peak magnetic field for the electromagnetic wave that constitutes the beam. (Hint: Recall the average intensity of electromagnetic waves. Also remember that intensity is power per unit area.)

1. Suppose you bought a red laser pointer (a cheap one you'd buy to play with a cat, not something you'd buy to try to light something on fire 3 miles away) (a) Look up online typical values for the power and wavelength of this kind of laser. (b) Estimate the radius of the beam. From this and the power in part (a), find the intensity of the laser light. (c) What are the electric field amplitude and the magnetic...

1-A parallel beam of light from a laser with a wavelength 450 nm, falls on a grating whose slits are 1.28 x 10-4 cm apart. How far (in cm) is the 1st order bright spot from the center of the pattern on a screen 3.4 m away? 2-A grating whose slits are 3.2x10-4 cm apart produces a third-order fringe at a 25.0° angle. What is the wavelength of light that is used?

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...
