Einstein was the first to use the equation E = hf to explain the photoelectric effect. It is known as the Planck equation, and h is called Planck's constant, because Max Planck had already proposed that when electromagnetic radiation was absorbed or emitted, energy was transferred in packets. That work earned Planck the 1918 Nobel Prize.

In this problem, you need Planck’s Constant, h; Boltzmann Constant, k; the speed of light, c; and the Stefan-Boltzmann Constant, . Lets enter these labels in column A, and their values in column B. Please note that Excel does not understand “x 10” in scientific notation. Instead use a capital “E” in its place.

Energy is equal to Planck’s constant times frequency. We can rearrange this equation to solve for frequency. 1.39 From Equation 1.15 we can derive an equation for the change in energy going from the n=1 to n=2 states for a hydrogen atom:.

h = Planck’s constant = 6.63 x 10-34 J-s ( = wavelength in meters ( = frequency in Hz (waves/s or 1/s or s-1. Draw a wave of light with high frequency Draw a wave of light with low frequency. How many Joules of energy are there in one photon of orange light whose wavelength is 630nm? (Work required) Violet light has a wavelength of 4.10 x 10-12 m.

Equation IV-3 therefore provides us a way of measuring Planck's constant. If we know the frequency of the light emitted from the LED and we can measure the diffusion potential, then is given by Eq. IV-3. However you will be finding the wavelength of the light, not its frequency. Since you know that , Eq.
