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.
A water wave, like all waves, transfers energy. When the. water wave meets the wall of the pool, it pushes against. the wall. The wall applies an equal and opposite force on. the water, sending the wave back in another direction. In the illustration. on the right, you can see water waves reflecting off a barrier. Sound and light waves reflect too. Sound waves reflecting off the. walls of a canyon produce an echo. Light waves reflecting off smooth. metal behind glass let you see an image of yourself in the mirror. The light waves bounce off the metal just as the water waves bounce. off the pool wall.
