Question:

(a) Show that if I2 = 10.0 I1, then (2 = (1 + 10.0 dB. (A factor of 10 increase in intensity corresponds to a 10.0 dB increase in intensity level.)
(b) Show that if I2 = 2.0 I1, then (2 = (1 + 3.0 dB. (A factor of 2 increase in intensity corresponds to a 3.0-dB increase in intensity level.
