An argon ion laser puts out 4.8 W of continuous power at a of 532 nm. The diameter of the laser beam is wavelength 5.6 mm. If the laser is pointed toward a pinhole with a diameter of 1.2 mm, how many photons travel through the pinhole per second? Assume that the light intensity is equally distributed throughout the entire cross-sectional area of the beam. (1 W1J/s) Express your answer using two significant figures. N= IVE ΑΣΦ 4 ? photons/s

What is the de Broglie wavelength of an oxygen molecule, O_(2), traveling at 521(m)/(s) ? Is the wavelength much smaller or much larger than the diameter of an atom (on the order of 100pm)?

How fast must a 132 g baseball travel in order to have a de Broglie wavelength that is equal to that of an x-ray photon with A = 100. pm? 4.0 m/s

A laser pointer is found to emit light with a frequency of 4.93 x 1014 Hz. Determine the wavelength (in nm) of a photon from this laser pointer. For large numbers, you can leave off the "x 10" portion here. For example, if you answer is 5.5 x 1025, you can type "5.5" here and write the full answer on your paper.

Enormous numbers of microwave photons are needed to warm macroscopic samples of matter. A portion of soup containing 445 g of water is heated in a microwave oven from 20.0°C to 98.0°C, with radiation of wavelength 1.55x10−2 m. How many photons are absorbed by the water in the soup?

The relationship between photons of light at various energies and wavelengths is Given by E=hv , c=v(wavelength) Therefore, when a photon of energy at wavelength of 275 nm is compared with photons of energy at wavelength of 390 nm and higher we have a decrease in the energy and its dissociation energy that would attack polymeric or chemical bonds of various structures. Therefore, the higher the wavelength  the lower the frequency or higher wavelengths have less energy than lower wavelengths 275nm is far greater energy than 390nm or higher. Given we have established light is composed of photons and high energy gamma radiation are also photons but of higher energy does the math for photochemistry given above apply to higher sources of photon energy from gamma and other sources of radiation? If so why or why not.  If there is a relationship what equations exist to compare and predict equivalence of standard electromagnetic model wavelength for actinic and visible and IR radiations to more…

Calculate the kinetic energy of an electron ejected from the surface of a sample of Rubidium (binding energy = 2.26 eV (where 1 eV = 1.60218 x 10-19 J) when the metal is subjected to photons having a wavelength of 325 nm.

A 100. W lamp emits red light of wavelength 680 nm. How many photons can the lamp generate in 26 seconds? (1W = 1J/s) Provide your answer in E- notation rounded to 2 significant figures.
