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.
1. A mechanical wave needs a medium for its propagation. An electromagnetic wave can travel through vacuum and it has the highest speed as it moves through the vacuum. Sound wave is a mechanical wave and light is an electromagnetic wave.2.A mechanical wave can be both transverse and longitudinal but an electromagnetic wave is a transverse wave. 3. The particles of the medium vibrate, when a mechanical wave passes through it.In an electromagnetic wave the oscillating parameters are the electric and magnetic field.n electromagnetic wave can travel through vacuum and it has the highest speed as it moves through the vacuum.
