The hydrogen spectral series can be expressed simply in terms of the Rydberg constant for hydrogen and the Rydberg formula. In atomic physics , Rydberg unit of energy , symbol Ry, corresponds to the energy of the photon whose wavenumber is the Rydberg constant, i.e. the ionization energy of the hydrogen atom in a simplified Bohr model.
The Việt Nam Quốc Dân Đảng (Vietnamese: [vìət naːm kwə́wk zən ɗa᷉ːŋ]; chữ Hán: 越南國民黨; lit. ' Vietnamese Nationalist Party ' or ' Vietnamese National Party '), abbreviated VNQDĐ or Việt Quốc, was a nationalist and democratic socialist political party that sought independence from French colonial rule in Vietnam during the early 20th century.

Rydberg had a value for his constant, but he had no idea where thatn constant came from. He didn't know that it was a simple (mathematically) function of the charge on the electron, the mass of an electron, the permitivity of free space, and the speed of light - plus another constant that he had no idea about because it wasn't discovered until ...
Quoc Trung first appeared on the 3rd season of Vietnam Idol in 2010. In 2011, Trung founded Thanh Viet Production, a record label and stage production company. Trung produced Uyen Linh's first album, My Own Dream (Giấc Mơ Tôi), released in February 2011.
Johannes (Janne) Robert Rydberg (Swedish: [ˈrŷːdbærj]; 8 November 1854 – 28 December 1919) was a Swedish physicist mainly known for devising the Rydberg formula, in 1888, which is used to describe the wavelengths of photons (of visible light and other electromagnetic radiation) emitted by changes in the energy level of an electron in a hydrogen atom.
The importance of the president has not remained constant throughout Vietnamese history. For instance, while Hồ Chí Minh was ranked as first member of the Politburo, the highest decision-making body in Vietnam, his successor, Tôn Đức Thắng, was a symbolic figure with little power. [7]
NSND Nguyễn Trung Kiên (Kiến Xương, Thái Bình, 5 November 1939 – 27 January 2021) [1] [2] [3] was a Vietnamese classical singer and People's Artist. [4] With the late Quý Dương and Trần Hiếu , Kiên was counted as the 3C Trio (Vietnamese Tam ca 3C, from tam ca 3 “cụ” ) - a term modelled on the Three Tenors .
Abridged Chronicles of Đại Việt) or Việt sử lược (chữ Hán: 越史略; lit. Abridged Chronicles of Viet ) is an historical text that was compiled during the Trần dynasty . The three-book work was finished around 1377 and covers the history of Vietnam from the reign of Triệu Đà to the collapse of the Lý dynasty . [ 1 ]
