1. Understand the units:
* Femtosecond (fs): A femtosecond is a very small unit of time, equal to 10⁻¹⁵ seconds.
* Speed of light (c): The speed of light in a vacuum is approximately 299,792,458 meters per second (m/s).
2. Calculate the distance:
* Formula: Distance = Speed × Time
* Distance = (299,792,458 m/s) × (3.3 × 10⁻¹⁵ s)
* Distance ≈ 9.9 × 10⁻⁷ meters
3. Express the answer in a more convenient unit:
* Nanometers (nm): 1 nanometer = 10⁻⁹ meters
* Distance ≈ 990 nanometers
Therefore, light travels approximately 990 nanometers in 3.3 femtoseconds.
