Below is a detailed set of short-answer type questions (including application-level questions) based on the "Sound Waves" chapter from the Kerala 10th Standard Physics curriculum. Each question is accompanied by a concise answer and, where relevant, a brief explanation to enhance understanding. The questions cover key concepts, definitions, calculations, and practical applications to ensure comprehensive exam preparation.These questions cover the chapter comprehensively, including definitions, calculations, and real-world applications, ensuring students are well-prepared for short-answer exam questions.
Some questions are:
What is forced vibration? Give an example.
Answer: Vibration of an object induced by an external vibrating object; e.g., a table vibrating when a tuning fork’s stem is pressed on it.
Explanation: The table vibrates due to the tuning fork’s vibrations, amplifying the sound.
Define resonance and provide one application.
Answer: Resonance occurs when the natural frequency of an object matches the frequency of an external force, causing maximum amplitude vibrations; e.g., used in radio tuning.
Explanation: Resonance enhances signal reception in radios by matching frequencies.
Why does a tuning fork produce a louder sound when its stem is pressed on a table?
Answer: The table undergoes forced vibration, amplifying the sound.
Explanation: The table vibrates at the tuning fork’s frequency, increasing the sound’s intensity.
