A one percentage point rise from current rates means an extra $61 in monthly payments on a $100,000, 30-year loan. Still, consider locking in your rate once you have set your closing date. For credit cards and home-equity loans, 2014 could be the last hurrah for low rates, says McBride.
1 In a vacuum, all electromagnetic waves travel at approximately 3 x 10 8 m/s-the fastest speed possible. 2  When electromagnetic waves travel through matter (for example, light through air or glass), they travel a bit slower than this but rarely less than half as fast as in a vacuum.
While the electromagnetic wave will travel at a speed of c (3 x 108 m/s) through the vacuum of interatomic space, the absorption and reemission process causes the net speed of the electromagnetic wave to be less than c. This is observed in the animation below.
