Fiber-optic cables are used widely for internet wiring, data transmission, and surgeries. When light passes through a fiber-optic cable, its intensity decreases with the increase in the length of the cable. If 1500 lumens of light enters the cable, the intensity of light decreases by 3.4% per meter of the cable.

Question

Write a function f(x) to represent the intensity of light, in lumens, when it has passed through x meters of the cable.

henrietepurina · Answer

Some scientists are trying to make a cable for which the intensity of light would decrease by 5 lumens per unit length of the cable. Can this situation be represented by a linear function? Justify your answer and write the appropriate function to represent this situation if 1500 lumens of light enter the cable.

masumanwar · Answer

light intensity decreasing inside the optical fiber is due to signal attenuation and can be expressed as a function of distance passing through the optical fiber as intensity i =I(Length of the optical fiber)
