- The speed of light in vacuum is defined to be c = 299,792,458 m/s = The permeability constant of vacuum is defined to be μ = 4 x 10-7 N. s²/C². Use these μ0²0 definitions to calculate the value of the permittivity of free space, to at least eight significant figures. (Enter your answer in c²/(N - m²).) HINT c²/(N - m²)LASIK eye surgery uses pulses of laser light to shave off tissue from the cornea, reshaping it. A typical LASIK laser emits a 1.0-mmmm-diameter laser beam with a wavelength of 193 nmnm. Each laser pulse lasts 13 nsns and contains 1.1 mJmJ of light energy. What is the power of one laser pulse? During the very brief time of the pulse, what is the intensity of the light wave?You have been taken to the emergency room. To get a constant update on your vital signs, equipment is attached to you, including a pulse oximeter. The pulse oximeter shines two LEDs on your finger to test how much oxygen is in your blood.
