Answer: a. The frequency of A is greater than the frequency of B.

c. The period of A is shorter than the period of B.

e. The wavelength of A is longer than the wavelength of B.

Step-by-step explanation:

The frequency of a sound, or the number of waves or cycles per second, determines its pitch. Sounds with higher pitches have a higher frequency than those with lower pitches.

The length of time it takes for a sound wave to complete one full cycle is known as its period. The relationship between the period and frequency is inverse. This implies that the time shortens as the frequency lengthens.

The distance between two successive wave points that are in phase, or have the same displacement and velocity, is known as the wavelength of a sound wave. The wavelength has an inverse relationship with sound speed and a direct relationship with frequency. Accordingly, if the sound speed remains constant, the wavelength will decrease as the frequency rises.

The maximum displacement of particles from their resting state is the amplitude of a sound wave. The pitch and frequency of the sound are unaffected by the amplitude. It solely controls the sound's volume or intensity.

The medium that sound travels through determines its speed. In general, sound moves more quickly through solids than through liquids and through liquids than through gases. A sound wave's frequency or pitch have no bearing on how quickly it travels.
