By what factor does the energy of a 1-nm X-ray photon ex- ceed that of a 10-MHz radio photon? How many times more energy has a 1-nm gamma ray than a 10-MHz radio photon?

How many photons per second are emitted by the antenna of a microwave oven if its power output is 1 kW at a frequency of 2560 MHz?  photons/s

For a body emitting blackbody radiation, the total power emitted is proportional to the 4th power of the body’s absolute temperature:(T in kelvins)and the wavelength of the emitted EM radiation that has the highest intensity is inversely proportional to the body’s absolute temperature according to:( in meters, T in kelvins)Assume an object is emitting blackbody radiation.   A body in a room at 300 K is heated to 3,000 K. The wavelength of the most intense EM radiation emitted by the body at 3,000 K is the wavelength of the most intense EM radiation at 300 K.

For light with a wavelength of 350 nm and with an intensity of /= 10-8 W/m², what is the number of photons/(m²s) in the light beam?

A material has a mass attenuation coefficient of 0.35 cm²/g (for a given photon energy) and has a density of 1 g/cm³. What is the thickness of the Half-Value Layer (HVL) of this material? (Note: the Half-Value Layer is the material thickness required to reduce an incident beam intensity by a factor of two).

After you calibrate the SpectroVis Plus spectrometer, you must a. run a full spectrum by selecting Sensors/Calibrate/Full Spectrum. O b. change the mode by selecting Sensors/Time-Based. Oc. collect a full spectrum of the sample to determine the wavelength of maximum absorbance. O d. change the mode by selecting Sensors/Data Collection.
