Explanation / Answer

1)

wavelength = 1.86*10^-6 m

wavelength = 1.86*10^-6 m

Here photon will be emitted

1/wavelength = R* (1/nf^2 - 1/ni^2)

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

1/wavelength = R* (1/nf^2 - 1/ni^2)

1/1.86*10^-6 = 1.097*10^7*(1/nf^2 - 1/4^2)

(1/nf^2 - 1/4^2) = 4.901*10^-2

1/nf^2 = 0.1115

nf^2 = 9

nf = 3

Answer: 3

2)

a)

Value of l is 2

So, valid values of ml are [-2, -1, 0, 1, 2]

so, ml can't be 3

Hence, this is unacceptable

b)

n must be a positive number

n can't be 0

Hence, this is unacceptable

c)

l can't be negative

l can't be -1

Hence, this is unacceptable

d)

This is Acceptable

e)

ms can be -1/2 or 1/2.

It can’t be 1

Hence, this is unacceptable
