Question

the distance between the two nearest molecules that are in phase with each other is called _____. answer options: select one of four wavelength amplitude frequency period

Explanation:

To solve this, we analyze each option:

• Wavelength: Defined as the distance between two consecutive points (like molecules) in phase in a wave.
• Amplitude: Maximum displacement from equilibrium, not a distance between in - phase points.
• Frequency: Number of oscillations per unit time, not a distance.
• Period: Time for one full oscillation, not a distance.

So the correct term is wavelength.

Answer:

wavelength
