The document discusses electromagnetic waves and their relationship to frequency, wavelength, and energy. It explains that energy and frequency are directly related through Planck's equation, while frequency and wavelength are inversely related through the electromagnetic wave equation. It also discusses absorption and emission spectra of atoms and how different substances absorb different wavelengths of light, appearing the color of the light not absorbed. Flame tests and emission spectra of various elements are mentioned.

2. HIGH FREQUENCY LOW FREQUENCY

3. Planck’s Equation E=hv E=energy in joules H=planck’s constant=6.63E-34J*s V=frequency (per second or Hz) The energy(E) and the frequency(V) of an electromagnetic wave are directly related. Electromagnetic Wave Equation C=λv C=speed of light=3.00E8m/s λ=wavelength in meters V=frequency (per second or Hz) Frequency and wavelength are inversely related. Wavelength and energy are inversely related.

5. Absorption and Emission Chart of Atoms

6. Flame test A flame test is a procedure used in chemistry to detect the presence of certain metal ions, based on each element's characteristic emission spectrum.

15. Spectrum: disconnected bands of color

16. Spectrum: disconnected bands of Orange, yellow and green

17. Emission Spectrums

18. More Emission Spectrums Halogen Flourescent

21. Light Absorbtion R O V Y B G Whatever color something is, is opposite the colors mainly being absorbed… White Light Here, all of the wavelengths (and different colors) are being absorbed. The green is the color that is actually being emitted. For example: If you were wearing a red shirt, green would be the color being most absorbed, along with all the rest.

22. According to the graphs… CUSO4 KMnO4 K2CrO4 Copper (II) sulfate absorbs it’s peak wavelength at around 680 nm, Thus, the color red is best absorbed. Potassium permanganate absorbs its peak wavelength at around 525 nm. In this substance the color greenish yellow is best absorbed. Potassium chromate absorbs its peak wavelength at around 440 nm. Hence, the hue greenish blue is best absorbed in this compound.
