4. Using the following information on the frequency and wavelengths of the colors of light, determine the energy of the photons of light emitted by each crystal. Fill in the answers on the table below. You
will need the formula E = hv where h = Planck's constant = 6.626 x 10-34 Js and v=frequency.
Color
Frequency (Hz)
Energy (J) of photon of light emitted
Red
4.5 x 1014 Hz
X 6.626 x 10-34 JS = 3.0 x 10-19 Joules
Orange
5.0 x 1014 Hz
X 6.626 x 10-34 JS =
Yellow
5.2 x 1014 Hz
Green
5.6 x 1014 Hz
Blue
6.6 x 1014 Hz
Violet
7.3 x 1014 Hz

In most resting cells, the concentration of sodium ions is higher outside of cells compared with the intracellular fluid. when cells are stimulated, sodium ion channels open, and sodium diffuses from the outside of the cell to the inside of the cell. sodium ion concentrations in a resting cell are an example of and sodium ion movement in a stimulated cell is an example of in most resting cells, the concentration of sodium ions is higher outside of cells compared with the intracellular fluid. when cells are stimulated, sodium ion channels open, and sodium diffuses from the outside of the cell to the inside of the cell. sodium ion concentrations in a resting cell are an example of and sodium ion movement in a stimulated cell is an example of potential energy; kinetic energy kinetic energy; potential energy the energy of motion; stored energy chemical work; energy stored in chemical bonds
