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 9

Describe how sound is produced in a guitar.

Describe the difference between noise and musical sound.

Explain the term 'echo' and state the condition necessary for an echo to be heard.

Explain why sound cannot travel through a vacuum.

A bat emits a sound and hears its echo after 0.2 seconds. If the speed of sound is 340 m/s, how far is the object from the bat?

A person hears thunder 5 seconds after seeing lightning. If the speed of sound is 340 m/s, how far away is the thunderstorm?

A sound wave travels through two different materials: Material A and Material B. In Material A, the speed of sound is 1500 m/s, and in Material B, it is 3000 m/s. If the frequency of the sound remains constant, how does the wavelength in Material B compare to that in Material A? Explain your reasoning.

A submarine sends out a sonar pulse and receives the echo after 4 seconds. If the speed of sound in seawater is 1500 m/s, calculate the distance to the object that reflected the sound.

Sound travels fastest in which of the following mediums? (1) Air (2) Water (3) Vacuum (4) Steel

What is the speed of sound in air at room temperature (approximately)? (1) 330 m/s (2) 1500 m/s (3) 5000 m/s (4) 3 × 10⁸ m/s

Which of the following frequencies is in the audible range for humans? (1) 5 Hz (2) 50 Hz (3) 50,000 Hz (4) 500,000 Hz

Which of the following is a longitudinal wave? (1) Light (2) Sound (3) X-rays (4) Radio waves

Fill in the blank: The ________ of a sound wave is the distance between two consecutive compressions or rarefactions.

Fill in the blank: The ________ of a sound wave is the maximum displacement of particles from their mean position.

Fill in the blank: The ________ of a sound wave is the number of vibrations per second.

The frequency of a sound wave determines its ________.

True or False: All sounds travel at the same speed in a given medium, regardless of their frequency.

True or False: Sound can travel through a vacuum.

True or False: The human ear is more sensitive to some frequencies than others.

True or False: The pitch of a sound increases as its frequency increases.
