A laser beam at a wavelength of 1.11 μm is coupled into an optic fiber, resulting in 138.2 mW of light inside the fiber initially. The fiber is 4.75 km long and has an absorption coefficienct of 1.562 dB/km. What light power, in mW, is at the end of the fiber?
In a physics lab, light with wavelength 490 nm travels in air from a laser to a photocell in 17.0 ns. When a slab of glass 0.840 m thick is placed in the light beam, with the beam incident along the normal to the parallel faces of the slab, it takes the light 21.2 ns to travel from the laser to the photocell. What is the wavelength of the light in the glass?
A possible means for making an airplane invisible to radar is to coat the plane with an
anti-reflective polymer. If radar waves have a wavelength of 3.30 cm and the index
of refraction of the polymer is n = 1.20, how thick would you make the coating?
State your answer in cm to the nearest 0.001cm.
