Term
| In the electromagnetic spectrum, Radiowaves or Gamma waves have a larger Wavelength? |
|
Definition
| Radiowaves, they are slower...thus they have a longer period, or longer distance to travel about an axis. |
|
|
Term
| In the electromagnetic spectrum, a larger wavelength corresponds to what type of a frequency (large or small)? |
|
Definition
| Larger wavelength means smaller frequency! |
|
|
Term
| The greater the frequency the _____ the wavelength, and _______the energy. |
|
Definition
| Smaller the wavelength, and greater the energy. |
|
|
Term

|
Definition
| Red = 750nm ------> Violet = 400nm |
|
|
Term
| Formula to relate energy to frequency? |
|
Definition
E = hf Energy = Plank's Constant x Frequency |
|
|
