Web14. apr 2024 · The intensity of sound is measured in decibels (dB), and exposure to sounds at or above 85 dB can cause hearing damage if exposure is prolonged or repeated. For example, a rock concert or music played through headphones at a high volume can reach levels of 100 dB or more, which can cause damage to the hair cells in the inner ear. Web19. mar 2024 · 2 Answers. Note that if we are 1 meter below the water, the intensity of light is 1 − 0.035 = 0.965 the intensity at the surface. If we submerge another meter, the intensity is 0.965 × 0.965 = ( 0.965) 2. Continuing, if we are x meters below the surface, the intensity is ( 0.965) x. We need to find x such that ( 0.965) x = 0.25.
