- The radius of the second Bohr orbit for the hydrogen atom is : (4) 2.12 A Radius of n^th Bohr orbit in H atom = 0.53 n²/Z For hydrogen Z = 1 Radius of 2^(nd )Bohr orbit in H atom = 0.53 ×2²/1 = 2.12 1
- Calculate the wavelength (in nanometer) associated with a proton moving at 1.0×103ms-1 (4) 0.40 nm Given m_p = 1.67×10⁻²⁷kg h = 6.63×10⁻³⁴Js v = 1.0×10³ms⁻¹ We know wavelength λ = h/mv ∴λ = 6.63×10⁻³⁴/(1.67×10^(-27 )× 1.0×10³)... 1
- if the kinetic energy of an electron is increased four times, the wavelength of the de-Broglie wave associated (2) Half Answer: The wavelength λ is inversely proportional to the square root of kinetic energy. So if KE is increased 4 times, the wavelen... 1
