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.
The speed (or sometimes you might see it called velocity) of a wave, v, is how far the wave travels in a certain time. Wave speed is measured in metres per second (m/s). All the electromagnetic waves travel at 300,000,000 metres per second (3 x 10 8 m/s).requency, wavelength, amplitude and wave speed. You need to know about these quantities used in waves-what they mean, the symbols used for them and the units used to measure them. The amplitude, a, of a wave is the distance from the centre line (or the still position) to the top of a crest or to the bottom of a trough.
