Use the Rydberg equation to calculate the predicted wavelength of light (in nm) emitted by a hydrogen atom as the electron moves from level n=8 to level n=2. Give your answer to four significant figures. Question 2 3pts Given the following emission spectrum for an unknown atom Calculate the wavelength of the blue-violet line (in nanometers). The units shown in the diagram above are centimeters. You should assume that the distance from the grating to the lamp is 0.268m, and that the grating has exactly 500 slits per millimeter
