Question:
The hydrogen spectrum shows 4 lines in the region visible spectral (this series is called the Balmer series: H (red): =656.3 nm,
H(blue-green): = 481.1 nm, H (purple): = 434.1 nm, and
H(purple): = 410.2 nm). Another series in the hydrogen spectrum is the Lyman series. Determine the wavelength of the fourth line of the Lyman series in m and nm (give two digits after the decimal point).
Q.2
If an electron has a speed of 2.05 x 10^6 m/s with a 1.5% uncertainty, how accurately can we measure position of the electron? The result corresponds to how many Bohr radii?
