A and B represent the displacement-distance graphs for two sound waves when they pass through air. Find the ratio between their loudness. fig A fig B
Find the amplitude of vibration of the particles of air through which a sound wave of intensity 2.0 × 10−6W m−2 and frequency 1.0 kHz is passing. Density of air =1.2 kgm−3and speed of sound in air =330ms−1
