Measuring light speed
WebNext, we calculate the speed of light using the relationship c= λf, where c is the speed of light in meters per second, λ is the wavelength in meters, and f is the frequency in hertz (Hz). To calculate the wavelength, first multiply your measure distance between marshmallow peaks by two. Measuring The Speed of Light Necessary materials:
