Question:
Approximate bandwidth required to transmit music is:
Approximate bandwidth required to transmit music is:
Show Hint
Audio transmission bandwidth depends on maximum audible frequency.
Updated On: Jun 17, 2026
- 20 kHz
- 2800 Hz
- 4.2 MHz
- 100 MHz
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Human audible range: \[ 20\ \text{Hz to } 20,000\ \text{Hz} \]
Step 2: Bandwidth required = highest frequency: \[ \text{Bandwidth} \approx 20\ \text{kHz} \]
Step 3: Hence correct option is 20 kHz.

- A wooden box lying at rest on an inclined surface of a wet wood is held at static equilibrium by a constant force $F$ applied perpendicular to the incline. If the mass of the box is $1\,kg$, the angle of inclination is $30^{\circ}$ and the coefficient of static friction between the box and the inclined plane is $0.2$, the minimum magnitude of $\vec{F}$ is (Use $ g = 10\,m/s^2$)
- A metre scale made of steel reads accurately at $25^{\circ} C$ . Suppose in an experiment an accuracy of $0.06\, mm$ in $1\,m$ is required, the range of temperature in which the experiment can be performed with this metre scale is (coefficient of linear expansion of steel is $ 11 \times 10^{-6} /^{\circ} \, C$ )
