Problem 16.23

(a) Estimate the power output of sound from a personspeaking in normal conversation. Use Table 16-2. Assumethe sound spreads roughly uniformly over a sphere centeredon the mouth, (b) How many people would it take toproduce a total sound output of 75 W of ordinary conversation?[Hint: Add intensities, not dBs.]

Step-by-Step Solution:
Step 1 of 3

Chapter 30: Quantum Physics The “ideal” blackbody absorbs all the light that is incident upon it and is an ideal radiator The distribution of energy in blackbody radiation is independent of the material from which the blackbody is constructed — it depends only on the temperature, T  Classical predictions were that the intensity increased rapidly with frequency,...
