Figure 23–67 shows a liquid-detecting prism device that might be used inside a washing machine. If no liquid covers the prism’s hypotenuse, total internal reflection of the beam from the light source produces a large signal in the light sensor. If liquid covers the hypotenuse, some light escapes from the prism into the liquid and the light sensor’s signal decreases. Thus a large signal from the light sensor indicates the absence of liquid in the reservoir. Determine the allowable range for the prism’s index of refraction \(n\).
