Question

match the right definition with the right word.
speed of sound
how fast sound travels through different types of matter
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 higl
interference
frequency
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” matches “speed of sound” (correctly matched in the image).

2. Medium

The definition “the type of matter that sound can travel through” matches “medium” (correctly matched in the image).

3. Echo

The definition “sound waves hit a hard flat surface and reflects back” matches “echo” (correctly matched in the image).

4. Hearing Range

The definition “for humans 20 Hz to 20,000 Hz other species can be high/low” matches “hearing range” (correctly matched in the image).

5. Interference

The missing definition for “interference” (not fully shown) should relate to the interaction of sound waves (e.g., “when two or more sound waves overlap and combine”).

6. Frequency

The definition “number of waves that pass a point in 1 second” matches “frequency” (correctly matched in the image).

For the “interference” term, the typical definition is “when two or more sound waves overlap and their amplitudes combine (constructive or destructive)”. If we assume the missing option aligns with this, the match is:

• interference → “when two or more sound waves overlap and combine (e.g., constructive/destructive interference)” (or the provided option’s full text, if available).

Final Matches (as per the image’s current state, with interference completed):

• speed of sound → how fast sound travels through different types of matter
• 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 high/low
• interference → [definition related to wave interaction, e.g., “when two sound waves overlap and their amplitudes add or cancel”]
• frequency → number of waves that pass a point in 1 second

(Note: If the “interference” dropdown has a specific option like “when two sound waves overlap and affect each other’s amplitude”, that is the correct match.)

Answer:

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

The definition “sound waves hit a hard flat surface and reflects back” matches “echo” (correctly matched in the image).

4. Hearing Range

The definition “for humans 20 Hz to 20,000 Hz other species can be high/low” matches “hearing range” (correctly matched in the image).
