Igcse Model Questions Vol1 2025 Physics Question 1
Practice objective / multiple choice question 1 from the 2025 Igcse Model Questions Vol1 Physics examination.
Two identical loudspeakers each produce a sound intensity level of \(80\ \text{dB}\) at a point that is \(2\ \text{m}\) from each speaker. The speakers are \(6\ \text{m}\) apart. Determine the sound intensity level at the point that is midway between the speakers (i.e. \(3\ \text{m}\) from each), assuming the intensities from the two speakers add incoherently.
