occurs when a body’s molecular wavelength sends vibrations to another body, resulting in the production of another sound wave

Natural frequency

Explanation:

Natural frequency is defined as the requency at which a system performs oscillation without any driving force.

All the objects produces sounds when they vibrates. Natural frequency occurs when an object is allowed to vibrate through the molecular wavelength ofanother body and the vibration produces sound wave.

Hence, the correct answer is natural frequency.

Interference.

Explanation:

Interference occurs when a body’s molecular wavelength sends vibrations to another body, resulting in the production of another sound wave

Hope this is correct. Have a great day.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
