Blue LED:
λ= 463.5 +/- 1.5 nm
h = (((463.5 +/- 1.5 nm)/109 nm)*2.320V)/(3*108 m/s)
H =
I'm trying to solve for h in this equation but I don't know how to make the units J*S because I have V*s and not eV*S so I don't know what to do.
Can you help me do the unit conversion?

7 (a)* The Planck constant h can be measured in an experiment using light-emitting diodes LEDs) Each LED used in the experiment emits monochromatic light. Te wavelength λ of the emitted photons is detemined during the manufacturing process and is provided by the manufacturer When the p.d. across the LED reaches a specific minimum value suddenly switches on emitting photons of light of wavelength the LED andi are related by the energy equation eVi hh flying lead Fig. 7.1 LED...
Given 2Al2O3 (s) --> 4Al(s) + 3O2 (g) (standard enthalpy change= 3351.4 kJ) a) What is the heat of formation of aluminum oxide? How do I find heat of formation from standard enthalpy change? I know how to do it when I'm given enthalpy, but they aren't the same thing- correct? Also, if this question gave me delta-H, I know that the heat of formation for 4Al = 0 and 3O2 = 0 because they are elementary species. This would...

Questions-Kevin Sparks of Blue Cross and Blue Shield of Kansas City had a difficult time convincing his people of the need for change. What would you have suggested he do before you read the case? What about afterwards? How did your recommendations change as a result?

I need help solving this problem. Thanks in advance. If correct, I will leave a like and a comment! Practice Problem 18.3 Constants Now let's look at the potential energy of a charge that is in the vicinity of two other charges. Suppose two electrons are held in place 10.0 cm apart. Point a is midway between the two electrons, and point b is 12.0 cm directly above point a. (a) Calculate the electric potential at point a and at...
Matlab & Differential Equations Help Needed I need help with this Matlab project for differential equations. I've got 0 experience with Matlab other than a much easier project I did in another class a few semesters ago. All we've been given is this piece of paper and some sample code. I don't even know how to begin to approach this. I don't know how to use Matlab at all and I barely can do this material. Here's the handout: Here's...
