Answer:
A. The pressure denoted as Pa and Pb at the surfaces of A and B in the tube is
PA= Pgas
PB= Patmos
B. The second sketch
C. The gas pressure is
Pgas= Patmos+ rho.g(h2-h1)
= 1atm + rho.g (h2-h1)

Answer:
Explanation:
The formula for hydrogen atomic spectrum is as follows
energy of photon due to transition from higher orbit n₂ to n₁

For layman series n₁ = 1 and n₂ = 2 , 3 , 4 , ... etc
energy of first line

10.2 eV
wavelength of photon = 12375 / 10.2 = 1213.2 A
energy of 2 nd line

= 12.08 eV
wavelength of photon = 12375 / 12.08 = 1024.4 A
energy of third line

12.75 e V
wavelength of photon = 12375 / 12.75 = 970.6 A
energy of fourth line

= 13.056 eV
wavelength of photon = 12375 / 13.05 = 948.3 A
energy of fifth line

13.22 eV
wavelength of photon = 12375 / 13.22 = 936.1 A

Wavelength = speed / frequency
(345 m/s) / (20,000 Hz) = 0.017 m
