AP Chemistry - Electromagnetism Worksheet #2
The Electromagnetic Spectrum
1.  What names do we give to various ranges of frequencies in the electromagnetic spectrum, beginning from the lowest frequency side?
2. What is meant by the "visible spectrum"?
3. What is the frequency in hertz of blue light having a wavelength of 425 nm?
4. A certain substance strongly absorbs infrared light having a wavelength of 6,500 nm.  What is the frequency in hertz of this light?
5. Yellow light has a wavelength of 600 nm. What is its frequency in hertz?
6. Green light has a wavelength of 550 nm. What is its frequency in hertz?
7. Intense microwaves have a frequency of 9.5 X 1011 Hz. What is the wavelength of these particular microwaves?
8. Infrared waves can be seen if you look down the railroad tracks or a road on a hot day. They heat the air as they go past causing the air to refract or bend the light.  If infrared rays of 9.75 X 1013 Hz are being reflected off the tracks or road what will be the size of  the wavelengths in micrometers?
9. A sunbather forgot their sunblock. On the beach they get a unheathly dose of UV radiation of 5.66 X 1016 Hz.  What is the wavelength of these particular UV waves?
