Question 1:

The wavelength: C

Wavelength is the distance between two consecutive identical points, such as from crest to crest.

*These A.I. responses have been individually checked to ensure they match the accepted answer, but explanations may still be incorrect. Responses may give guidance but the A.I. might not be able to answer the question! This is particularly the case for questions based on diagrams, which the A.I. typically cannot interpret.

Question 2:

The amplitude: D

Amplitude is the maximum displacement from the rest position (the dashed center line) to a crest or trough.

Question 3:

Increasing the volume of a sound means it is louder, which corresponds to greater energy transfer.
For a sound wave, louder volume = greater amplitude (the maximum displacement of particles in the medium).

• Frequency (A) determines pitch, not loudness.

• Wavelength (C) is related to frequency and speed; changing volume doesn’t directly change it.

• Wave speed (D) depends only on the medium (temperature, pressure, etc.), not on amplitude.

So the measurement that changes to increase volume is the amplitude.

Answer: B. The amplitude.

Question 4:

Based on oscilloscope display conventions:

• Height (amplitude) → loudness (tall = loud, short = quiet)

• Number of waves in a fixed width → frequency (more waves = higher pitch, fewer waves = lower pitch)

• Wavelength is inversely related to frequency in a fixed box width (more waves = shorter wavelength, fewer waves = longer wavelength)

  A high amplitude, long wavelength sound → A (tall height, a few waves)

Question 8:

Among the options:

• A. Sound waves → longitudinal (oscillations parallel to energy transfer)

• B. Water waves (on the surface) → transverse (oscillations perpendicular to energy transfer; though water molecules also have some circular motion, surface waves are generally classified as transverse for basic physics purposes)

• C. Light waves → transverse (electromagnetic)

• D. Microwaves → transverse (electromagnetic)

Answer: A. Sound waves
