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.
Actually, radio waves travel very quickly through space. Radio waves are a kind of electromagnetic radiation, and thus they move at the speed of light. The speed of light is a little less than 300,000 km per second. At that speed, a beam of light could go around the Earth at the equator more then 7 times in a second.
