High-power lasers are used to compress a plasma (a gas of charged particles) by radiation pressure. A laser generating radiation pulses with peak power 190O MW is focused onto 1.2 mm2 of high-electron-density plasma. Find the pressure exerted on the plasma if the plasma reflects all the light beams directly back along their paths.

What is the energy (in eV) of a photon with 150 nm wavelength?

At what distance from a 125 W electromagnetic-wave point source does Emax = 15.1 V/m?

Emergency responders for radioactive material incidents normally use the inverse square law of radiation to estimate the separation distance from the radioactive source. If a source has an intensity of 3.125 R/min at one foot from the source, solve for the distance in feet to the 5 mR/min boundary. Show your solution, including assumptions.

High-power lasers are used to compress a plasma (a gas of charged particles) by radiation pressure. A laser generating radiation pulses with peak power 1200 MW is focused onto 0.80 mm² of high-electron-density plasma. Find the pressure exerted on the plasma if the plasma reflects all the light beams directly back along their paths. Number Units

True or False UV light have a high ability to move through materials such as glass, paper, pus, feces, and petri dish lids. True False

From Fig. 9.19, what are the values of x, y, and z for light with a 540-nmwavelength? For light with a 600 nm wavelength?

Genesis gets accepted to a Dental School in Idaho and when she arrives,she cannot find good signål. To fix this problem,Genesis orders a 2m long antenna on Amazon, and ottaches it to her phone.If the antenna carries a 900 mC chorge, what will be the force (mognitude and direction) on a 5 MC that is 30 cm (0.3)away from its Center? You have to derive the equation for the Electric field.

Do it asap

Assume that your body (with temperature of 310 K) can be approximated as a blackbody. What is the typical wavelength of the radiation from your body? Is this radiation visible, infrared, X-ray, or radio?
