Assume the core of an optical fibre has an index of refraction of 1.82 and the index of refraction of the classing is 1.51. If a laser is to be pointed into the end of the fibre, but is "tipped" to one side by θ degrees, how much can the laser be "tipped" before thelight no longer continues down the fibre?
