What makes optical fiber most effective at emitting light
Infrared (IR) Light: This is the dominant choice for modern fiber optic systems. Why? Lower Attenuation: IR light experiences less loss (attenuation) as it travels through the fiber compared to visible light. This means signals can travel much farther without needing. Multimode fibers can support many thousands of modes. In order to accurately study optical modes, the complete Maxwell equations are to be solved.

What is the sensing principle of fiber optic sensors
A fiber optic sensor measures a physical quantity by modulating the intensity, spectrum, phase, or polarization of light traveling through the optical fiber system. It's a device that converts light rays into electronic signals. This signal can then be measured by an instrument or interpreted by a user.
