Observe the bright incandescent bulb through the spectrometer and sketch the spectrum in the space below. Be careful to match up the colors you see with the correct wavelengths. Look at the dim incandescent bulb through the spectrometer. INCANDESCENT BULB How does the spectrum of the dim light differ from the spectrum of the bright light? Is the wavelength of orange light the same as it was before? Is the wavelength of light the same as it was before? Is the color of light determined by its wavelength? Explain using your observations so far. EMISSION SPECTRA Observe the gas discharge tubes through the spectrometer and sketch the spectra in the spaces below. Be careful to match up the colors you see with the correct wavelengths. HYDROGEN HELIUM NEON MERCURY ARGON OXYGEN Do any of the elements have identical spectra? If so, which ones? Describe the differences in the spectrum of the incandescent light and the spectra of the discharge tubes. Look closely at a discharge tube that is not on and an incandescent light. What makes the light for each of these: a gas, a liquid, or a solid? Part 2: Does the Evidence Match the Conclusion?
