For example, if a buyer obtains a seven-year balloon mortgage to purchase a home, he has seven years of equal monthly payments at a fixed interest rate. This rate is often lower than what the buyer would otherwise be able to secure under a traditional mortgage loan.
When sound reflects off a special curved surface called a parabola, it will bounce out in a straight line no matter where it originally hits. Many stages are designed as parabolas so the sound will go directly into the audience, instead of bouncing around on stage.
The density of the wave will be the lowest just past downstream of the wave. So, if the wave is moving from left to right (making the right side downstream), then just past the right side of the wave will have the lowest density. A compression wave occurs when there's a lot of pressure build up. Think of air flowing through an air duct. All of a sudden, the duct gets smaller, making this compression form a wave. The downstream side of the wave will have the lowest density because the waves themselves will be farther apart. Report
