A submarine is using an experimental device designed to measure the distances of nearby objects. A laser is aimed at the object and turned on. The light travels to the object, is reflected, and returns to the submarine. The device measures the time lag between the instant that the laser is turned on and the instant the reflected light is received back at the device. The wavelength of the laser is 532.0 nm=532.0 x 10^9 m. The index of refraction of the water is n=1.33, and the speed of light in a vacuum is 3.0 x 10^8 m/s. what is the frequency of the light? what is the speed of the light in the water? The laser is aimed at an object and turned on. The time for the reflected light to return is found to be 4.433 x 10^-6 s. How far away is the object?
