When a powerful laser is employed in the Earth's atmosphere, the accompanying electric field may ionize the air, transforming it into a plasma that reflects the laser light. Electric breakdown occurs in dry air at 0°C and 1 atm when field amplitudes above around 3:00 Mv/m a). At this maximum intensity, how much Power can a cylindrical beam with a diameter of 4.03 mm deliver? Note Answer must be in W.

A perpendicular polarized plane wave with an electric field amplitude of 18 V/m and a frequency of 5 GHz propagates from free space (&1-1, 1-1, 1-0) to another medium with parameters &2 = 3, 2-1, 62-0. If the angle of incidence is 60°; determine the electric field at the interface in the second dielectric.

Mammography is an x-ray imaging procedure for breast cancer diagnosis and screening. Assume that 20ke V x-ray is used in mammography. Also assume that the breast of a patient is 6 cm in thickness (soft tissue), and the propagation speed of x-ray photons in soft tissue is about the same as in vacuum. How long will it take for x- ray photons to travel through the breast?

A stream of electrons with a linear number density of 3.10 x 1011 electrons/meter are accelerated from rest by a 62.0-V potential difference applied across two parallel plates. The electrons then pass through an aperture in the high voltage plate and into a current collector where the beam current is measured. Note: The mass of an electron is 9.11 x 10-31 kg. (a) What is the magnitude of the electric field between the plates if they are 2.07 m apart? V/m (b) What is the final velocity of each electron? m/s (c) What is the beam current? A

A UV lamp used to disinfect objects emits radiation with an rms electric field strength of 65 N/C. Calculate the energy absorbed by a circular target of radius 2 cm that is placed under the lamp for 231 seconds.(Give your answer in joules but don't include the units.)
