Question

match the right definition with the right word.
speed of sound
medium
echo
hearing range
interference
frequency
doppler effect
number of waves that pass a point in 1 second
amplitude
decibels
the type of matter that sound can travel through
sound waves hit a hard flat surface and reflects back
how fast sound travels through different types of matter - example water is 1482 m/s
for humans 20 hz to 20,000 hz other species can be higher or lower
doppler effect
number of waves that pass a point in 1 second

Explanation:

To solve this matching problem, we analyze each term and its corresponding definition:

1. speed of sound: The definition "how fast sound travels through different types of matter - example water is 1482 m/s" describes the speed of sound.
2. medium: The definition "the type of matter that sound can travel through" matches medium (as sound needs a medium like air, water, etc., to travel).
3. echo: The definition "sound waves hit a hard flat surface and reflects back" is the definition of an echo.
4. hearing range: The definition "for humans 20 Hz to 20,000 Hz other species can be higher or lower" refers to the hearing range (the range of frequencies a species can hear).
5. frequency: The definition "number of waves that pass a point in 1 second" is the definition of frequency (measured in Hz, where 1 Hz = 1 wave per second).

Final Matches:

• speed of sound → how fast sound travels through different types of matter - example water is 1482 m/s
• medium → the type of matter that sound can travel through
• echo → sound waves hit a hard flat surface and reflects back
• hearing range → for humans 20 Hz to 20,000 Hz other species can be higher or lower
• frequency → number of waves that pass a point in 1 second

(Note: The term "interference" and "doppler effect" were not fully matched in the provided options, but based on the visible definitions, the above are the correct matches for the shown terms.)
