'Decibel' is the unit used for ..measuring:-

Speëd of light.

Intensity of sound

Intensity of heat.

Intensity of earthquake

- Decibel is a unit used to measure the intensity of sound.

- Your understanding is correct here. The decibel (dB) quantifies sound levels and helps compare different sound intensities.

- Option 1: Speed of light is measured in meters per second (m/s).

- The speed of light is a constant value often denoted as 'c' and is approximately 299,792,458 m/s.

- Option 3: Intensity of heat is measured in terms like joules, watts, or calories.

- Heat intensity is typically related to the energy transfer, not measured in decibels.

- Option 4: Intensity of earthquakes is measured using the Richter or Mercalli scales.

- Earthquakes are quantified by their seismic activity, not in decibels.

Your answer aligns with this information:
