Sound class 8 Extra Questions And Answers
What is sound? Answer: Sound is a form of energy that travels through a medium as a longitudinal wave.
How is sound produced? Answer: Sound is produced by the vibration of an object. The vibration sets the molecules of the medium in motion, creating a disturbance that propagates as a sound wave.
What is the difference between a sound wave and a light wave? Answer: Sound waves are longitudinal waves, while light waves are transverse waves. Sound waves require a medium to propagate, while light waves can travel through a vacuum.
What is the frequency of a sound wave? Answer: The frequency of a sound wave is the number of complete oscillations or cycles per second. It is measured in Hertz (Hz).
What is the amplitude of a sound wave? Answer: The amplitude of a sound wave is the maximum displacement of a particle from its equilibrium position. It determines the loudness of the sound.
What is an echo? Answer: An echo is a reflected sound wave that returns to the listener with a delay of at least 0.1 seconds after the original sound wave.
What is the difference between reflection and refraction of sound? Answer: Reflection occurs when a sound wave bounces back off a surface, while refraction occurs when a sound wave bends as it passes through a medium with a different density.
How does the human ear detect sound? Answer: The human ear detects sound through the vibration of the eardrum. The vibrations are then transmitted to the inner ear, where they are converted into nerve impulses and sent to the brain for interpretation.
What is the range of human hearing? Answer: The range of human hearing is typically between 20 Hz and 20,000 Hz.
How can sound be measured? Answer: Sound can be measured using a device called a sound level meter. The unit of measurement for sound is decibels (dB).
FAQs on Sound for class 8th
Q: What is sound and how is it produced? A: Sound is a form of energy that travels through a medium as a longitudinal wave. It is produced by the vibration of an object. The vibration sets the molecules of the medium in motion, creating a disturbance that propagates as a sound wave.
Q: What are the properties of sound? A: The properties of sound include frequency, amplitude, wavelength, velocity, and pitch.
Q: What is the difference between a high-pitched and a low-pitched sound? A: High-pitched sounds have a higher frequency than low-pitched sounds. The frequency of a sound wave determines the pitch of the sound.
Q: What is an echo and how is it produced? A: An echo is a reflected sound wave that returns to the listener with a delay of at least 0.1 seconds after the original sound wave. It is produced when a sound wave encounters a reflecting surface, such as a wall, and bounces back to the listener.
Q: What is the difference between noise and music? A: Noise is an irregular sound that lacks melody or harmony, while music is a form of organized sound that has melody, harmony, and rhythm.
Q: What is the speed of sound and how is it affected by different factors? A: The speed of sound is approximately 343 meters per second in air at room temperature. It is affected by factors such as temperature, pressure, and humidity.
Q: What is the difference between reflection and refraction of sound? A: Reflection occurs when a sound wave bounces back off a surface, while refraction occurs when a sound wave bends as it passes through a medium with a different density.
Q: What is the range of human hearing? A: The range of human hearing is typically between 20 Hz and 20,000 Hz.
Q: How can sound be measured? A: Sound can be measured using a device called a sound level meter. The unit of measurement for sound is decibels (dB).
