question 19 help

Use the following information to answer the next question Observations relating to light I. The shadow cast by a small bead placed in laser light has a bright spot in the middle II. Adjusting the intensity of the light incident on a piece of metal has no effect on the energy of the photoelectrons produced III. Electrons confined to a region of space can exist only in discrete energy levels 13. Which row below gives the model required to explain each of the observations above? Row Observation I wave particle particle wave Observation II particle particle particle wave Observation III wave wave particle wave

Learning Goal: To understand the Bohr model of the hydrogen atom. In 1913 Niels Bohr formulated a method of calculating the different energy levels of the hydrogen atom. He did this by combining both classical and quantum ideas. In this problem, we go through the steps needed to understand the Bohr model of the atom. Part A Consider an electron with charge -e and mass m orbiting in a circle around a hydrogen nucleus (a single proton) with charge +e. In the classical model, the electron orbits around the nucleus, being held in orbit by the electromagnetic interaction between itself and the protons in the nucleus, much like planets orbit around the sun, being held in orbit by their gravitational interaction. When the electron is in a circular orbit, it must meet the condition for circular motion: The magnitude of the net force toward the center, F, is equal to mv²/r. Given these two pieces of information, deduce the velocity v of the electron as it orbits around the nucleus. Express your…

The dark-adapted eye can supposedly detect one photon of light of wavelength 500 nm. Suppose that 100 such photons enter the eye each second. Part A Estimate the intensity of the light. Assume that the diameter of the eye's pupil is 0.50 cm. Express your answer in watts per square meter. Templates Symbols undo redo Teset keyboard shortcuts help I= W/m² ܬܘܝܐ

Tutorial How much more energy does a 73 nm photon have than a 7870 nm photon? Does the 73 nm photon move at a greater speed than the 7870 nm photon? Which photon has a higher frequency? Part 1 of 4 The energy of a photon depends on its wavelength by the relation: E = hc Part 2 of 4 We have an energy relation for each photon, where subscripts 1 and 2 represent the 73 nm and 7870 nm photons, respectively. We can use these relations to express the energy of the first photon in terms of the two wavelengths and the energy of the second photon. E₁ E₂ E₁ E₁ = hc ^₁ hc 1₂ 12E2 ^₁ E₂
