Common Mistakes to Avoid
Assuming light travels at a uniform speed in all mediums
This can lead to errors in calculations; for example, light travels slower in water at about 75% of its speed in a vacuum.
✓ Always use the speed of light in a vacuum (299,792,458 m/s) for precise calculations.
Neglecting to account for time delays in communication systems
For instance, a 1,000 km fiber optic cable introduces a latency of about 5 ms, which can impact high-frequency trading.
✓ Calculate signal delay based on the medium's speed, not just the speed of light in a vacuum.
