What happens to the wavelength if the sound wave slows down and the frequency dont change?
Wavelength and frequency are locked together in an inverse proportionality. If the frequency of a wave is constant, the wavelength of the wave will be constant. Increase one and the other decreases. Decrease one and the other increases. That said, let's look at the dynamics of a tsunami, which may be the general direction in which this was heading. In a tsunami, the wave moves very quickly in the open ocean, and it has a long wavelength. As it closes on shore, the leading edge of the wave slows down as the sea bottom "rises up" to meet the wave. As the leading edge of the wave continues to slow down, the "rest of the wave" begins to "catch up" with the wave front. This causes the wave to build; its height will increase. The actual wavelength is decreasing (and its frequency will be increasing), and the wave continues to slow down. Higher and higher it will build, and then it will break on the shore and carry inland.
What happens if water is heated?
When it reaches 212°F it begins to boil. When boiling occurs the water evaporates into steam. We use hot water for many things, bathing, cooking, cleaning.
What decibel is deafening?
Starting at 85 decibels, ear plugsshould be worn because hearing damage begins. At 140 decibels, no matter what the frequency or duration of time, serious damage is inflicted to the ears and it is extremely painful. At 145 decibels, vision begins to blur due to vibration. 163 decibels is the minimum glass breaking sound level.Go to this chart for a more detailed explanation.http://makeitlouder.com/Decibel%20Level%20Chart.txt
