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.
How fast do waves travel? The speed of a wave-its wave speed-is related to its frequency and wavelength, according to this equation: wave speed (metre per second) = frequency (hertz) Ã wavelength (metre). For example, a wave with a frequency of 100Hz and a wavelength of 2m travels at 100 Ã 2 = 200m/s. Check your understanding of the equation by having a go at this activity.
