- Use the Rydberg equation to calculate the wavelength (in nm) of the hydrogen Balmer series line having nouter = 5 and ninner = 2. After calculating delta E, take the absolute value, and solve for frequency using Equation (1). Use this frequency in Equation (2) to solve for the wavelength.Express your answer to 3 significant figures.I need the answer as soon as possible................. ........................... .......................... The classic Millikan oil drop experiment was the first to obtain an accurate measurement of the charge on an electron. In it, oil drops were suspended against gravity by a vertical electric field. microscope Assume the oil drop to be 2.50 um in radius and have a density of 897 kg/m3. (a) Find the weight of the drop. (b) If the drop has a single excess electron, find the magnitude of the electric field strength needed to balance its weight. N/C
