at the rim of the glass
where air meets water
on the table
at the eraser
Three glasses are filled with different amounts of water. When the each rim is tapped, the number of vibrations is recorded. Here are the results: 500 vibrations per second, 600 vibrations per second, and 700 vibrations per second. Which one has the higher pitch?
500 vibrations per second
600 vibrations per second
700 vibrations per second
all are the same pitch
The glass on the left is empty. You tap the rim of all three glasses with a pencil and notice that each one produces a different pitch. Why does each one produce a different pitch?
Each one echoes differently.
Sound travels faster in water and slower in air (gas).
The amount of water in the glass affects how fast it vibrates.
All three produce the same pitch.
