If frequency of sound produced by a siren increases from 400 to 1200 Hz while the wave amplitude remains constant, the ratio of intensity of the 1200 Hz to that of 400 Hz wave will If frequency of sound produced by a siren increases from 400 to 1200 Hz while the wave amplitude remains constant the ratio of intensity of the 1200 Hz to that of 400 Hz wave will November 1, 2020 Category: Arihant Physics by D.C Pandey , Chapter 16 - Waves , Volume 1 , Facebook Messenger WhatsApp Share this:TwitterFacebook Related
