Angstrom to Meter Conversion Problem This example problem demonstrates how to convert angstroms to meters: The spectra of the element sodium have two bright yellow lines, known as the "D lines," with wavelengths of 5,889.950 Å and 5,895.924. What are the wavelengths of these lines in meters? Solution 1 Å = 10-10 m Set up the conversion so the desired unit will be canceled out. In this case, we want meters to be the remaining unit.wavelength in m = (wavelength in Å) x (10-10) m/1 Å)wavelength in m = (wavelength in Å x 10-10) mFirst line:wavelength in m = 5,889.950 x 10-10) mwavelength in m = 5,889.950 x 10-10 m or 5.890 x 10-7 mSecond line:wavelength in m = 5,885.924 x 10-10) mwavelength in m = 5,885.924 x 10-10 m or 5.886 x 10-7 m Answer Sodium's D lines have wavelengths of 5.890 x 10-7 m and 5.886 x 10-7 m respectively.
