Question

match the right definition with the right word. hearing range medium speed of sound interference frequency echo

Explanation:

Since the definitions for the terms (hearing range, medium, speed of sound, interference, frequency, echo) are not provided in the question, we can't perform the matching directly. However, here are the standard definitions to help with the matching:

• hearing range: The range of frequencies that a person (or animal) can hear. For humans, it's typically 20 Hz to 20,000 Hz.
• medium: A substance (solid, liquid, gas) through which a wave (like sound) travels.
• speed of sound: The rate at which sound waves propagate through a medium (e.g., ~343 m/s in air at 20°C).
• interference: The combination of two or more waves (sound, light, etc.) that overlap in space, resulting in a new wave pattern (constructive or destructive).
• frequency: The number of wave cycles (vibrations) per unit time, measured in hertz (Hz).
• echo: A reflected sound wave that arrives after a delay (e.g., from a wall or cliff).

To complete the matching, pair each term with its corresponding definition using these explanations. For example:

• hearing range → [definition about frequency range of audible sound]
• medium → [definition about the substance for wave travel]
• speed of sound → [definition about sound’s propagation rate]
• interference → [definition about wave combination]
• frequency → [definition about cycles per unit time]
• echo → [definition about reflected sound]

If you provide the list of definitions (the options in the dropdowns), I can help match them precisely.
