For a hydrogen-like atom, classify these electron transitions by whether or not they consequence within the absorption or emission of sunshine. Ignoring signal, which transition is related to the best power change n = 3 to n = 5 n = 3 to n = 2 n = 2 to n = 1 n = 1 to n = 3

1)

when theres transition from increased state to decrease

state, it entails emission

when theres transition from decrease state to increased

state, it entails absorption

So, Absorption are:

n=3 to n=5

n=1 to n=3

emission are:

n=2 to n=1

n=3 to n=2

2)

a)

Right here photon will probably be captured and itll excite the

atom

1/lambda = R* (1/nf^2 1/ni^2)

R is Rydberg fixed. R = 1.097*10^7

1/lambda = R* (1/nf^2 1/ni^2)

1/lambda = 1.097*10^7* (1/5^2 1/3^2)

lambda = 1.29*10^-6 m

lambda = 1290 nm

use:

E = h*c/lambda

=(6.626*10^-34 J.s)*(3.0*10^8 m/s)/(1.29*10^-6

m)

= 1.541*10^-19 J

b)

Right here photon will probably be emitted

1/lambda = R* (1/nf^2 1/ni^2)

R is Rydberg fixed. R = 1.097*10^7

1/lambda = R* (1/nf^2 1/ni^2)

1/lambda = 1.097*10^7* (1/2^2 1/3^2)

lambda = 6.563*10^-7 m

lambda = 656 nm

use:

E = h*c/lambda

=(6.626*10^-34 J.s)*(3.0*10^8 m/s)/(6.563*10^-7

m)

= 3.029*10^-19 J

Since that is emitted power, signal will probably be

damaging

So,

E = 3.029*10^-19 J

C)

Right here photon will probably be emitted

1/lambda = R* (1/nf^2 1/ni^2)

R is Rydberg fixed. R = 1.097*10^7

1/lambda = R* (1/nf^2 1/ni^2)

1/lambda = 1.097*10^7* (1/1^2 1/2^2)

lambda = 1.215*10^-7 m

lambda = 122 nm

use:

E = h*c/lambda

=(6.626*10^-34 J.s)*(3.0*10^8 m/s)/(1.215*10^-7

m)

= 1.635*10^-18 J

Since that is emitted power, signal will probably be

damaging

So,

E = 1.635*10^-18 J

D)

Right here photon will probably be captured and itll excite the

atom

1/lambda = R* (1/nf^2 1/ni^2)

R is Rydberg fixed. R = 1.097*10^7

1/lambda = R* (1/nf^2 1/ni^2)

1/lambda = 1.097*10^7* (1/3^2 1/1^2)

lambda = 1.032*10^-7 m

lambda = 103 nm

use:

E = h*c/lambda

=(6.626*10^-34 J.s)*(3.0*10^8 m/s)/(1.032*10^-7

m)

= 1.926*10^-18 J

Clearly power is largest for d

Reply: n=1 to n=3
