Term | Definition |
---|---|
Speed of light (C) | 3.00 X 10^8 m/s |
Amplitude | Height of wave |
Wavelength (Lambda) | distance covered by the wave in meters |
Frequency (V) | Number of waves that pass a point in a given period of time |
When is the energy of the wave higher? | When the frequency is higher (shorter wavelength) |
Plank's Constant (h) | 6.626x10^-34 m/s |
Color of light is determined by | Wavelength or frequency |
Threshold Frequency | Minimal frequency needed before electrons are emitted (regardless of intensity) |
Solve for Wavelength (Lambda) | and E=hc/lambda |
Solve for Frequency (V) | E=hv |
Binding energy | One photon at the threshold frequency gives the electron just enough energy to escape the atom |
Avagoadro's number | 6.02x10^23 (use when converting KJ/Mole to Photons) |
