Consider a laser pen. Construct a problem in which youcalculate the number of photons per second emitted by thepen. Among the things to be considered are the laser pen’swavelength and power output. Your instructor may also wishfor you to determine the minimum diffraction spreading in thebeam and the number of photons per square centimeter thepen can project at some large distance. In this latter case,you will also need to consider the output size of the laserbeam, the distance to the object being illuminated, and anyabsorption or scattering along the way.
A laser produces light of wavelength 725 nm in an ultrashortpulse. What is the minimum duration of the pulse if the minimum uncertaintyin the energy of the photons is 1.0%?
3. 2. In one experiment, the spectra of an incandescent lamp behaving as a black body were measured with a temperature T, an emitting wavelength of peak intensity A, and an electric current I, if the potential difference was increased. The drop across the filament is 8 times and the current through it is doubled. What is the wavelength emitted at the maximum intensity? Given that the electrical energy can be converted to heat energy without loss. waste of energy Choice 4 A

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).

An unknown material was ground to a fine powder and subjected to x-ay diffraction measurement using a Bruker V8 system with Cukα radiation with wavelength λ= 1.452 Å. The following 2θ values were recorded: 28.5o, 47.4o Identify the miller indices for the two XRD peak.
A 5 pm photon undergoes Compton scattering with an electron and emerges at 66∘ to it original direction of motion. Find the wavelength of the scattered photon in picometers. Give your answer with two decimal places please.
What is the wavelength in meters of a photon generated by an electron going from n = (8.000x10^0) to n= (1.00x10^0)? Answer to 3 significant figures and in scientific notation. Sorry about the two n values, I can either do scientific notation need for the answer or you have to enter the answer without scientific notation. I can't change between them. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: Answer x10 units
I need help with this question. Originally I got 3 degrees for the answer, but it appears that this is incorrect and I don't know what went wrong. Here is the question: Electrons with an energy of 0.610 eV are incident on a double slit in which the two slits are separated by 60.0 nm. Electron speed is 4.63e+05 m/s and the de Broglis wavelength of the electrons is 1.57 nm. What is the angle between the two second-order maxima in the resulting interference pattern. I really appreciate the help!
Sketch a plot of the current / versus voltage V across an ideal photocell when visible light is incident on the cell. Note that the "amplitude" factor lo should be assumed to be negative.
