Is frequency equal to intensity?
Is frequency equal to intensity? If intensity of a wave is proportional to frequency, why doesn’t sound level, in general, depend on frequency. i.e. Higher frequency, higher intensity, higher sound level. The loudness of a sound does not seem to depend on frequency. But according to the equation above, intensity DOES depend on frequency. How […]
