The intensity of sound follows a pattern commonly referred to as an Inverse Square Law as supported by the intensity equation for a spherically uniform radiation. Explain what this means using examples of changing distance such as doubling, tripling and halving the distance, and what that does to the intensity. Describe in detail one other physical phenomena that obeys an inverse square law.

Explain the di erence between sound intensity and sound intensity level in terms of what they measure You're listening to two speakers. One plays a 440 Hz tone, and the other plays a 442 Hz tone, both at the same volume. Name the kind of interference you'd hear, and describe how the volume of the sound you hear would vary, as speci cally as possible You're standing at rest on the oor. If you then rise up on your ptoes,...

In October 1991, the Sacramento City Council adopted a law to reduce the allowed sound intensity level of the much despised leaf blowers from their current level of about 95 dB to 70 dB by May 1992.With the new law, what is the ratio of the new allowed intensity to the previously allowed intensity?

The formula for measuring sound intensity in decibels D is defined by the equation D = 10log(I/I0) where I is the intensity of the sound in watts per square meter and I0 = 10−12 is the.

The formula for measuring sound intensity in decibels D is defined by the equation D = 10log(I/I0) where I is the intensity of the sound in watts per square meter and I0 = 10−12 is the lowest level of sound that the average person can hear. How many decibels are emitted from a rock concert with a sound intensity of 4.7 · 10−1 watts per square meter?

Consider the possibility that the inverse square law for light might provide a solution to Olber’s paradox. Assume a uniform distribution of stars with n stars per unit volume, each of identical luminosity L. Now imagine two thin, spherical shells of radii r1 and r2 centered on Earth, and let the thickness of each shell be ∆r. Determine the ratio of the energy flux received on Earth from the two shells, in terms of r1 and r2. Can the inverse...

Use the inverse square law to estimate how the brightness of the Sun would change if you moved from Earth at 1 AU to Saturn's location at 10 AU (i.e., give a fraction or percentage, not magnitude). Then, the brightest known star is R136a1 with an absolute magnitude of -12.5, explain why you cannot make a precise determination of its brightness as seen from Earth without more information
