4. A student performing the experiment described in this module collected the following and hydrogen. Helium Lines a scale reading rle reading 12.3 112 E length, 396.4 402.6 412.0 414.4 43 447.1 471.3 10.7 10.6 9.1 temelength, 492.2 501.6 504.8 587.5 667.8 706.5 6.5 4.6 8.7 7.7 Hydrogen Lines scale readings 10.7 9.3 7.1 3.6 (1) Plot a calibration curve relating the scale readings to the known values for the wavelengths of emission of helium. (2) Using the calibration curve prepared in (1), determine the wavelength of the hydrogen line at scale reading 10.7. answer (3) What color is the light emitted at the wavelength determined in (2) (4) Calculate the energy (AE) corresponding to the wavelength determined in (2). (5) Determine the level (1) from which the electron fell to 1 in (2) answer 2 to produce the emission discussed answer
