Characteristics of Sound 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 Characteristics of Sound.
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.

Describe what happens to the pitch of a sound if its frequency increases.
Explain why sound cannot travel through outer space.
If two sounds have the same frequency but different amplitudes, how will they differ?
Name the three main characteristics of sound.
