An optical technician measures the speed of light in a newly developed optical fiber. The widely accepted theoretical value for the speed of light in this fiber is 1.91 × 108 m s-1.
Using the same apparatus and method, the technician records four consecutive measurements in a single session:
Measurement 1: 2.05×108 m s−1 \text{Measurement 1: } 2.05 \times 10^8\text{ m s}^{-1} Measurement 1: 2.05×108 m s−1 Measurement 2: 2.06×108 m s−1 \text{Measurement 2: } 2.06 \times 10^8\text{ m s}^{-1} Measurement 2: 2.06×108 m s−1 Measurement 3: 2.04×108 m s−1 \text{Measurement 3: } 2.04 \times 10^8\text{ m s}^{-1} Measurement 3: 2.04×108 m s−1 Measurement 4: 2.05×108 m s−1 \text{Measurement 4: } 2.05 \times 10^8\text{ m s}^{-1} Measurement 4: 2.05×108 m s−1Which option correctly describes these measurements?
