Problem 16.84

Workers around jet aircraft typically wear protectivedevices over their ears. Assume that the sound levelof a jet airplane engine, at a distance of 30 m, is 130 dB,and that the average human ear has an effective radiusof 2.0 cm. What would be the power intercepted byan unprotected ear at a distance of 30 m from a jetairplane engine?

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,...
