Using Orders of Magnitude in Physics Calculations

This video tutorial explains the concept of orders of magnitude, focusing on how to express very small and large numbers using powers of 10. It covers the use of decimal prefixes for both small and large numbers, providing examples of converting units like nanometers and mega ohms. The tutorial includes two examples: calculating the speed of a wave using frequency and wavelength, and calculating electric current using charge and time. The video emphasizes the importance of understanding decimal prefixes and their corresponding multipliers for physics calculations.
