The tests need to use a more precise value for a certain constant.

Tholian on 19 Mar 2012

The +/- 25% in the problem statement does not match the test results.

James on 20 Jul 2012

Agreed on both counts.

Gareth Lee on 22 Apr 2015

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
