Answer 1

Hint:Recall the various characteristics related with a wave. Also recall the characteristics related with the sound wave. Recall the definitions of these characteristic physical quantities and check which of the characteristics given in column A matches with the description given in the column B given in the question.

Complete step by step answer:
There are various characteristics related to the wave such as amplitude, time period, frequency, wavelength, etc. The amplitude of a wave is the maximum displacement of the particles in the medium from its mean position. Therefore, the amplitude of vibration is the displacement of the vibrating body from its original point. Hence, the correct match for the 1 in column A is d in column B.

The time period of a wave is the time required for the wave to complete one cycle of the wave.Therefore, the time period of vibration of the wave is the time taken by a vibrating body to complete one cycle of vibration.Hence, the correct match for the 2 in column A is b in column B.

The frequency of a wave is the number of cycles of the wave completed by the wave in one second or unit time.Therefore, the frequency of vibration is the number of oscillations that a body completes in one sec. Hence, the correct match for the 3 in column A is e in column B.

There are some more characteristics related to a sound wave such as loudness and pitch.The loudness of the sound wave is the characteristic related with the sound wave which depends on amplitude of the sound wave.Hence, the correct match for the 4 in column A is c in column B.

The pitch of the sound wave is the characteristic related with the sound wave which depends on frequency of the sound wave.Hence, the correct match for the 5 in column A is in column B. Therefore, the matches for the columns in A and B are 1-d, 2-b, 3-e, 4-c, 5-a.

Hence, the correct option is B.

Note: The students may get confused between the pitch and loudness of the sound. The loudness of the sound is proportional to amplitude of the wave and pitch of the sound is proportional to frequency of the wave. The students should be careful while determining the match of these characteristics given in column A with their description given in column B.
