Problem

A spectrometer's fitting sheet reports the wavelength of a spectral line as λ=589.2934 nm,u(λ)=0.0876 nm.\lambda = 589.2934\ \mathrm{nm}, \qquad u(\lambda) = 0.0876\ \mathrm{nm}. ((a)) Write the result in the house form λ=λˉ±u(λ)\lambda = \bar\lambda \pm u(\lambda), with the uncertainty rounded to two significant figures and the value rounded to the same decimal place. ((b)) Write the same result in the concise bracket notation.
