Multiple choice audible, infra and ultra sound with its application study of sound physics

The audible range of frequency is

  1. 20 Hz to 20,000 Hz

  2. 40 Hz to 40,000 Hz

  3. 60 Hz to 60,000 Hz

  4. 10 Hz to 20,000 Hz

A Correct answer
Explanation

Human ear can hear sound having frequency range from $20 \ Hz$ to $20 \ kHz$.

So, human beings can't hear sound having frequency below $20  \ Hz$ and above $20,000 \ Hz$.

Multiple choice audible, infra and ultra sound with its application study of sound physics

Out of the following, which frequency is not clearly audible to the human ear ?

B Correct answer
Explanation

The frequency range of human hearing is about 20 Hz to 20 KHz. This range of frequency is known as audible range. Human cannot hear the sound with frequency above or below this audible range. Hence the sound with frequency 30,000 Hz cannot audible to human ear

Multiple choice audible, infra and ultra sound with its application study of sound physics

The direction of motion of a particle at any instant is given by

  1. Velocity

  2. Loudness

  3. Frequency

  4. Phase
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Velocity is a vector quantity defined as the rate of change of displacement with respect to time, which explicitly specifies both the speed and the direction of motion of a particle at any given instant.
