Sound Characteristics and Numericals Puzzles
Puzzle 1: Loudness and Amplitude
Which physical property of sound determines its loudness?
Hint: It is related to the height of the sound wave.
Answer: Amplitude of the sound wave.
Puzzle 2: Pitch and Frequency
What determines the pitch of a sound?
Hint: It depends on the number of vibrations per second.
Answer: Frequency of the sound wave.
Puzzle 3: Quality of Sound
Which property helps us distinguish between two sounds of the same loudness and pitch?
Hint: It is also called timbre.
Answer: Quality of sound (Timbre).
Puzzle 4: Numerical on Loudness
A sound wave has an amplitude of 5 units. If the amplitude increases to 10 units, by how many times will the loudness increase?
Hint: Loudness is proportional to the square of amplitude.
Answer: Loudness will increase by 4 times (2² = 4).
Puzzle 5: Numerical on Frequency
A vibrating tuning fork produces a sound wave of frequency 256 Hz. How many vibrations occur in 5 seconds?
Hint: Multiply frequency by time.
Answer: 256 x 5 = 1280 vibrations.
