As per the condition E=n⋅h⋅ν (vitality = number of photons times Planck's consistent circumstances the recurrence), on the off chance that you partition the vitality by Planck's steady, you ought to get photons every second. 
Eh=n⋅ν → the term n⋅ν ought to have units of photons/second 
Number of photons = 15

Given:
- 2n1 + 3n2 = 18
- 2n2 - 3n1 = 6

Finding the values of n1 and n2:
- Simplifying the equations:
- 2n1 + 3n2 = 18 (equation 1)
- 2n2 - 3n1 = 6 (equation 2)
- Solving the equations simultaneously, we get:
- n1 = 3
- n2 = 4

Calculating the total number of photons emitted:
- When electron transitions from n2 to n1 shell, the total number of photons emitted is equal to the energy difference between the two shells divided by the energy of each photon.
- Energy difference = E2 - E1 = 1/R(1^2 - 1/n2^2)
- Energy of each photon = hc/λ
- Total number of photons = Energy difference / Energy of each photon

Substitute the values:
- n1 = 3, n2 = 4
- Energy difference = 1/R(1 - 1/4)
- Energy of each photon = hc/λ
- Total number of photons = Energy difference / Energy of each photon

Calculating the total number of photons:
- Energy difference = 1/R(3/4)
- Energy of each photon = hc/λ
- Total number of photons = Energy difference / Energy of each photon
Therefore, the total number of photons emitted when the electron transitions to the n1 shell is 15.
So, the correct answer is:

b) 15

Read the following text and answer the following questions on the basis of the same:Electron Microscope Electron microscopes use electrons to illuminate a sample. In Transmission Electron Microscopy (TEM), electrons pass through the sample and illuminate film or a digital camera.Resolution in microscopy is limited to about half of the wavelength of the illumination source used to image the sample. Using visible light the best resolution that can be achieved by microscopes is about ~200 nm. Louis de Broglie showed that every particle or matter propagates like a wave. The wavelength of propagating electrons at a given accelerating voltage can be determined byThus, the wavelength of electrons is calculated to be 3.88 pm when the microscope is operated at 100 keV, 2. 74 pm at 200 keV and 2.24 pm at 300 keV. However, because the velocities of electrons in an electron microscope reach about 70% the speed of light with an accelerating voltage of 200 keV, there are relativistic effects on these electrons. Due to this effect, the wavelength at 100 keV, 200 keV and 300 keV in electron microscopes is 3.70 pm, 2.51 pm and 1.96 pm, respectively.Anyhow, the wavelength of electrons is much smaller than that of photons (2.5 pm at 200 keV). Thus if electron wave is used to illuminate the sample, the resolution of an electron microscope theoretically becomes unlimited. Practically, the resolution is limited to ~0.1 nm due to the objective lens system in electron microscopes. Thus, electron microscopy can resolve subcellular structures that could not be visualized using standard fluorescence microscopy.Q. Wavelength of electron as wave at accelerating voltage 200 keV is
