Explanation:

• Sound is a longitudinal mechanical wave that propagates by making compressions (high pressure) and rarefactions(low pressure) in its propagating medium. 

• The amplitude of wavelength is the maximum distance the particle oscillating moves from the mean position.
• The frequency of the wave is the number of times one complete cycle of compressions 

• More the frequency more is the pitch of the sound, the sound is having more shrillness. 
• The more the amplitude the more is the loudness of the sound. 

So, loudness depends upon the amplitude.

Important Points 

• The Pitch of the sound depends upon frequency. 
• Mathematically, loudness is directly proportional to the square of the amplitude. 

L ∝ A2

Here the pattern is,

Sum of the three digits of a number is equal to 5.

203 – 2 + 0 + 3 = 5,

500 – 5 + 0 + 0 = 5,

600 – 6 + 0 + 0 = 6

401 – 4 + 0 + 1 = 5
