Chapter 24 Electromagnetic Waves 6. A neodymium-glass laser emits short pulses of high-intensity of electromagnetic waves. The electric field of such a laser pulse has an rms value of Ems = 8.0 x 10' N/C. (a) Determine the average power of each pulse that passes through the cross-sectional area of of the laser beam A -5.05 x 10-5 m. (b) Determine the average intensity of this laser in W/m². - 4-
1. (3 points) Consider a beam of light of wavelength 514.5 nm emitted by a laser. The diameter of the beam is 2.00 mm and there are 1.30 X 1018 photons emitted per second. a) Find the peak electric field for the electromagnetic wave that constitutes the beam. b) Find the peak magnetic field for the electromagnetic wave that constitutes the beam. (Hint: Recall the average intensity of electromagnetic waves. Also remember that intensity is power per unit area.)
An industrial laser is used to burn a hole through a piece of metal. The average intensity of the light is 1.60 × 10 9 W/m². What is the rms value of the electric field in the electromagnetic wave emitted by the laser?
