Calculate the energy of one photon of yellow light that has a wavelength of 589nm.

When i do this on the calculator i get 5.093378608 E -4 . How is that the same as 5.09 x 10^14 s-1. I am having a hard time with what the anser is on the calculator and the answer in the book.  

Then I get the final answer of 3.37 x 10^-19

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.

ok whats the question if not i cannot you i need question and need a thing to answer
