8. What is the intensity of 100 dB noise level?

Correct Answer: Correct answer is: (C) 1X 10$^{-2}$ w/m$^{2}$.

Exam Relevance: GATE, GRE, MCAT, Physics Olympiad

Difficulty: Moderate

Concept notes: The decibel (dB) scale is logarithmic, and the intensity level in decibels is given by the formula $ L_I = 10 \log_{10} \left( \frac{I}{I_0} \right) $, where $ I $ is the intensity of the sound and $ I_0 $ is the reference intensity (typically $ 1 \times 10^{-12} $ W/m$^2$ for sound in air).

Common Mistakes: A common mistake is to confuse the logarithmic nature of the decibel scale with a linear scale, leading to incorrect intensity calculations.

Explanations: To find the intensity corresponding to 100 dB, we use the formula $ L_I = 10 \log_{10} \left( \frac{I}{I_0} \right) $. Given $ L_I = 100 $ dB and $ I_0 = 1 \times 10^{-12} $ W/m$^2$, we can solve for $ I $: \[ 100 = 10 \log_{10} \left( \frac{I}{1 \times 10^{-12}} \right) \] Divide both sides by 10: \[ 10 = \log_{10} \left( \frac{I}{1 \times 10^{-12}} \right) \] Convert from logarithmic to exponential form: \[ 10^{10} = \frac{I}{1 \times 10^{-12}} \] Multiply both sides by $ 1 \times 10^{-12} $: \[ I = 10^{10} \times 10^{-12} = 10^{-2} \text{ W/m}^2 \] Thus, the intensity of 100 dB noise level is $ 1 \times 10^{-2} $ W/m$^2$.

Option Analysis:

Option A: Incorrect, as $ 1 \times 10^2 $ W/m$^2$ is much higher than the correct value.
Option B: Incorrect, as $ 1 \times 10^{-3} $ W/m$^2$ is lower than the correct value.
Option C: Correct, as $ 1 \times 10^{-2} $ W/m$^2$ matches the calculated intensity.
Option D: Incorrect, as $ 1 \times 10^3 $ W/m$^2$ is much higher than the correct value.
