- 4. Two coherent beams having parallel electric fields are described by TT E₁ = 5 cos(ks₁ · wt + 3) E₂ = 3 cos +7) (ks₂ - wt+ With amplitudes in kV/m. the beams interfere at a point P where the phase difference due to path is π/4. At the point of superposition, calculate the net irradiance.We have an interferometer set up so that no light is reaching the photodetector (that means there is complete destructive interference at the output of the interferometer). If the wavelength of the laser for the interferometer has a wavelength of 1.0 μm, how far does an arm mirror need to move to get maximum light at the output of the interferometer?E17P8
- Information is stored on an audio compact disc, CD-ROM, or DVD disc in a series of pits on the disc. These pits are scanned by a laser beam. An important limitation on the amount of information that can be stored on such a disc is the width of the laser beam. Explain why this should be, and explain how using a shorter-wavelength laser allows more information to be stored on a disc of the same size. With which color of light can the Hubble Space Telescope see finer detail in a distant astronomical object: red, blue, or ultraviolet? Explain your answer.Problem 3: When laser light is passed through two narrow slits separated by 148 µm, an interference pattern is observed on a screen 1.67 m away.
