Can You See a Single Photon? The wavelength corresponding to the maximum sensitivity of the human eye is 510 nm, the limit of sensitivity of the dark-adapted eye has been shown to be correspond to a 100 ms flash of light of total energy 240 eV. (Little Shop of Physics- Colorado State University) 1 J = 6.241509 x 1018 eVa) What is the energy of a single photon at this wavelength?b) How many photons does the flash contain?c) If 60%...
The answer of number 2 is E=4.18 *10^-6 ev And number 4 is E=2.07 ev 2. What should be the energy of an electron so that the associated electron waves have a wavelength of 600 nm? ince the visible region spans between approximately 400 nm and 700 nm, why can the electron wave mentioned in Problem 2 not be seen by the human eye? What kind of device is necessary to detect electron waves? 4. What is the energy of...
Plz do number 4, number 2 answer is 4.18*10^-6 ev 2. What should be the energy of an electron so that the associated electron waves have a wavelength of 600 nm? 3. Since the visible region spans between approximately 400 nm and 700 nm why can the electron wave mentioned in Problem 2 not be seen by the human eye? What kind of device is necessary to detect electron waves? 4. What is the energy of a light quantum (photon)...

A; You are measuring the lattice constant (the distance between planes of atoms) of a sample crystal using X-ray diffraction. The crystal structure is known to be SC or simple cubic. Your X-ray tube produces X-rays with a wavelength of 0.630 nm. You observe the first diffraction peak at an angle of 28.5°. What is the lattice constant of the crystal? _____??? B: Suppose that at least 21.5 eV is needed to free an electron from a particular element, i.e.,...

answer is not 122 or 97.2 Review Constants Let's use the Bohr model equations to explore some properties of the hydrogen atom. We will determine the kinetic, potential, and total energies of the hydrogen atom in the n=2 state, and find the wavelength of the photon emitted in the transition n = 2 →n=1.

questions 1, 2, 3, 4 please answer all of them. Question 1: Which photon energies will excite the Hydrogen atom when its electron is in the ground state (Hint: there are 5 named on the simulator, though there are more Question 2: Starting from the ground state, press the L, button twice in succession (that is, press it a second time before the electron decays). What happens to the electron? Question Complete the energy mange values for the excited state...
Please answer all of these questions with brief explanations. Thank you! Name: Doppler ultrasound PROBLEM 4-8 points Ultrasound is the name we give to sound waves that have a higher frequency than 20 kHz, which is the maximum frequency our ears can respond to. For this problem, assume that high frequency sound waves travel through human tissue at 1500 m/s (about the speed of sound in water). 2 points] (a) Ultrasound equipment for diagnostic imaging typically uses frequencies between 1...
