Two light pulses traversing identical path lengths \(L\) through air and glass.
Two light pulses traversing identical path lengths \(L\) through air and glass.
Two identical laser pulses are emitted simultaneously toward parallel detectors separated from the sources by the same distance \(L\). Pulse 1 travels entirely through air, where the index of refraction is \(n_1 = 1.00\). Pulse 2 travels through a block of transparent glass of length \(L\) having an index of refraction \(n_2 = 1.50\). What is the ratio of the transit time of Pulse 1 to the transit time of Pulse 2, \(\dfrac{t_1}{t_2}\)?
