Characteristics of Sound

Physics ⇒ Waves and Sound

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.
See sample questions for grade 11
Define the term 'timbre' in relation to sound.
Describe how temperature affects the speed of sound in air.
Describe the relationship between amplitude and loudness of a sound wave.
Explain why sound cannot travel through outer space.
Explain why two sounds with the same frequency and amplitude can still be distinguished from each other.
State the difference between noise and musical sound.
What is the formula relating speed (v), frequency (f), and wavelength (λ) of a sound wave?
What is the main factor that determines the speed of sound in a medium?
A person hears a thunder 5 seconds after seeing the lightning. If the speed of sound in air is 340 m/s, how far away did the lightning strike?
If the amplitude of a sound wave is doubled, how does its intensity change? (1) It doubles (2) It quadruples (3) It halves (4) It remains the same
Which of the following best describes ultrasonic sound? (1) Sound with frequency below 20 Hz (2) Sound with frequency above 20,000 Hz (3) Sound with frequency between 20 Hz and 20,000 Hz (4) Sound that cannot travel through solids
Which of the following frequencies would be considered infrasonic? (1) 10 Hz (2) 100 Hz (3) 1,000 Hz (4) 10,000 Hz

The frequency of a sound wave determines its ________.
The loudness of a sound is measured in ________.
The time taken for one complete vibration of a sound wave is called its ________.
The unit of frequency is ________.
True or False: Sound can travel through a vacuum.
True or False: The pitch of a sound increases as its frequency increases.
True or False: The wavelength of a sound wave increases as its frequency increases, if the speed of sound remains constant.
