1) How many photons are emitted during a transition from a higher level orbit to a lower level orbit? a)1 b)2 c)3 d)4

2) True/False? An electron can transition from any allowed orbit to any other allowed orbit.

3) What is the wavelength of light emitted when an electron drops from the 3 to the 2 shell in a hydrogen atom?

Expert Solution

1. E = E2-E1 =n hV

E = nhV n =1,2,3 ....

E2-E1 = hV

n=1

a.1 answer

2 . True

electron transition from higher energy level to lwer energy level and lower energy level to higher energy level.

3. 1/ = RH[1/n1² -1/n2²]

1/ = 109677[1/2² --1/3²]

= 109677[0.25-0.11]

= 109677*0.14

= 15354.78 = 6.5*10^-5 cm

Please answer these three questions (1) In what ways are the photons emitted during stimulated emission related to the incident (stimulating) photons? (2) What conditions must a collection of atoms meet in order to amplify an incident beam of light? (3) Very briefly describe how these requirements are met in a helium

Although not visible through your spectroscope, photons of both higher and lower energy are being emitted from the hydrogen discharge tube. Calculate one transition that would lead to the emission of a UV (ultraviolet) photon. (UV light has a wavelengths between approximately 4 and 400 nm). Of an IR (infared) photon? (IR light has wavelengths between approximately 700 and 700,000 nm).

7. Suppose the number of photons emitted by an atom during a one-minute time window can be modeled as a Poisson random variable with parameter ? = 2. Now, suppose you watch the atom for two minutes, and the number of emitted photons in each minute is an independent Poisson process. Calculate the probability that you see exactly one photon during the two minutes. (Hint: this is the probability that you see no photons in the first minute and one...

1. How many photons at 586 nm must be absorbed to melt 6.55 × 102 g of ice? (It takes 334 J to melt 1 g of ice at 0° C. On average, how many H2O molecules does one photon convert from ice to water? 2. The highest speed limit in the United States is 85.0 mph on an isolated stretch of rural interstate in Texas. What is the speed limit in kilometers per hour? (1 mi = 1609 m)....

An electron in a hydrogen atom undergoes a transition from an orbit with quantum number ni to another with quantum number nf.

An electron in a hydrogen atom undergoes a transition from an orbit with quantum number ni to another with quantum number nf. Vi and Vf are respectively the initial and final potential energies of the electron. If Vi/ Vf = 6.25, then the smallest possible nf.
