The light we see from the sun is emitted by the photosphere, which has a temperature of about 5800 Kelvin and emits a peak wavelength of about 500 nm (which appears green to most humans). But the temperature of the core, where nuclear fusion occurs, has a temperature of about 16,800,000 K. What is the wavelength of the peak radiation emitted at the sun's core? {You will need to use scientific notation to enter your answer. Remember, in WebAssign, you must use an "e" to represent "x10" in scientific notation.}
a) 1.79e-7 nm
b) 3.03e-9 nm
c) 1.75e-10 nm
d) 8.93e-12 nm
