Examine the fluorescent light and incandescent light spectra
Examine the fluorescent light and incandescent light spectra. Draw your observations for the fluorescent and incandescent light spectra and upload your drawings below. Your drawing should clearly show the relative positions of each band on the scale and the bands should either be drawn in the correct color or labelled with a description of the color.Compare the two observed spectra above. How are they similar? WHY are they different?
Draw your observations for the spectra of the three discharge tubes that you observed and upload your drawings below. Your drawing should clearly show the relative positions of the major bands on the scale and the bands should either be drawn in the correct color or labelled with a description of the color.

Using your spectroscope, you observe a light source and see several strong, distinct lines. Is this source continuous or discrete? Given a line with a wavelength corresponding to 500 nm, calculate the energy of the emitted light. Given a photon emitted from a hydrogen lamp with a wavelength of 434 nm, identify the correct transition in the Balmer series. R_h = 2.18 *10^(-18) J. (Hint: it is in the visible region of the electromagnetic spectrum) Looking through your spectroscope, you...

I was having trouble with some lab question on atomic emission
spectra.
Also answer the following questions about your observations: Are the lines present in the hydrogen spectrum the same lines predicted by the Bohr model the atom? Which lines, if any, are missing? Why might there be lines missing? Compare the spectral lines from your unknown substance to the other spectra you observed. Based on these comparisons, what is the identity of the unknown substance? Are there any general...

question 7 and 8
Purpose To examine the properties of polarized light and the mathematical relationship describing the intensity of linearly polarized light (Malus'law). In addition, the lab will investigate different ways light can be polarized Overview This lab is the first of three labs exploring the properties of electromagnetic waves. Electromagnetic waves are composed of oscillating electric and magnetic fields. As discussed in the lecture the electric and magnetic field vectors are mutually perpendicular to each other. Light waves...
