Sound Production
Physics ⇒ Waves and Sound
Sound Production starts at 7 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Sound Production.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 10
A bell is rung inside a jar from which air has been removed. What will you observe and why?
A tuning fork is struck and placed near a ping pong ball suspended by a thread. The ball starts to move. What does this demonstrate?
Calculate the frequency of a sound wave with a speed of 340 m/s and a wavelength of 0.85 m.
Describe how sound is produced in a drum.
Describe the process by which a guitar string produces sound.
Explain why sound cannot travel through a vacuum.
Explain why sound produced by a tuning fork becomes fainter as you move away from it.
Explain why your voice sounds different when you hear a recording of it compared to when you speak.
State the law of reflection of sound.
What is sound and how is it produced?
What is the function of the larynx in sound production in humans?
What is the relationship between the frequency and pitch of a sound?
A flute and a violin play the same note at the same loudness. However, they sound different. What property of sound is responsible for this difference?
A metal rod is clamped at one end and struck at the other. Explain how the length and material of the rod affect the pitch of the sound produced.
A sound wave has a frequency of 500 Hz and travels at 1500 m/s in water. Calculate its wavelength.
A student notices that when she speaks into one end of a long metal pipe, the sound is heard more clearly at the other end than when she speaks through open air. Explain why this happens.
A student observes that when a glass is filled with more water, the sound produced when tapping the glass becomes higher in pitch. Explain the reason for this observation.
Explain why the sound produced by plucking a stretched string becomes louder when the string is plucked with greater force.
A loudspeaker produces a sound wave with a frequency of 1,000 Hz and a wavelength of 0.34 m in air. Calculate the speed of sound in air based on these values.
A scientist is designing a musical instrument that uses metal bars of different lengths. Explain how the length of each bar affects the pitch of the sound produced, and why.
