Wavelength, frequency and energy

This is simple drill and practice involving electromagnetic radiation. On loading, and when you press "Refresh", one of the cells in the first table will be filled. Enter the two missing values and press "Check Ans" Results appear in the second table. Pay close attention to the dimensions. You should continue with a problem until you get it correct, but you can generate a new problem at any time.Use "e" notation for sci notation. Thus, 2.3e-4 equals 2.3*10-4
