for certain x-ray radiation, given frequency in petahertz, give wavelength in nanometer, must be accurate +/- 25%
The tests need to use a more precise value for a certain constant.
The +/- 25% in the problem statement does not match the test results.
Agreed on both counts.
it seems the test result is centimeter, not nanometer
A great physics problem. However, it does not work with a more accurate value of speed of light, namely
c = 299,792 kilometers per second
definitely agree with your comments
