Question

10 matching 3 points match the right definition with the right word. hearing range medium speed of sound when sound waves come in contact with each other doppler effect amplitude for humans 20 hz to 20,000 hz other species can be higher or lower the type of matter that sound can travel through decibels number of waves that pass a point in 1 second sound waves hit a hard flat surface and reflects back

Explanation:

• hearing range: The definition "for humans 20 Hz to 20,000 Hz other species can be higher or lower" matches as hearing range refers to the frequency range an organism can hear.
• medium: The definition "the type of matter that sound can travel through" matches as a medium is the material (solid, liquid, gas) that sound waves propagate through.
• speed of sound does not have a correct match in the given options yet. Let's re - check the remaining options:
• "when sound waves come in contact with each other" is about interference (not speed of sound).
• "doppler effect" is about change in frequency due to relative motion (not speed of sound).
• "amplitude" is about the maximum displacement of a wave (not speed of sound).
• "decibels" is a unit of sound intensity (not speed of sound).
• "number of waves that pass a point in 1 second" is frequency (not speed of sound).
• "sound waves hit a hard flat surface and reflects back" is reflection (not speed of sound). Maybe there is a mistake in the options or the problem setup, but based on the given, the correct matches for the first two are:
• hearing range - for humans 20 Hz to 20,000 Hz other species can be higher or lower
• medium - the type of matter that sound can travel through

Answer:

• hearing range: for humans 20 Hz to 20,000 Hz other species can be higher or lower
• medium: the type of matter that sound can travel through
• (speed of sound: no correct match from the given options)
