The Beer-Lambert Law. A beam of light enters a medium such as water or smoky air with initial intensity
The constant
(“mu”), called the coefficient of absorption, varies with the medium. Use this law for Exercises 62 and 63.
Light through smog. Concentrations of particulates in the air due to pollution reduce sunlight. In a smoggy area,

- Find the constant of proportionality. E varies jointly with I and R. If R=25 and I=5, then E=125.arrow_forwardTsunami Waves and BreakwatersThis is a continuation of Exercise 16. Breakwaters affect wave height by reducing energy. See Figure 5.30. If a tsunami wave of height H in a channel of width W encounters a breakwater that narrows the channel to a width w, then the height h of the wave beyond the breakwater is given by h=HR0.5, where R is the width ratio R=w/W. a. Suppose a wave of height 8 feet in a channel of width 5000feet encounters a breakwater that narrows the channel to 3000feet. What is the height of the wave beyond the breakwater? b. If a channel width is cut in half by a breakwater, what is the effect on wave height? 16. Height of Tsunami WavesWhen waves generated by tsunamis approach shore, the height of the waves generally increases. Understanding the factors that contribute to this increase can aid in controlling potential damage to areas at risk. Greens law tells how water depth affects the height of a tsunami wave. If a tsunami wave has height H at an ocean depth D, and the wave travels to a location with water depth d, then the new height h of the wave is given by h=HR0.25, where R is the water depth ratio given by R=D/d. a. Calculate the height of a tsunami wave in water 25feet deep if its height is 3feet at its point of origin in water 15,000feet deep. b. If water depth decreases by half, the depth ratio R is doubled. How is the height of the tsunami wave affected?arrow_forwardFind the constant of proportionality. I is inversely proportional to R. If R=20, then I=50.arrow_forward
- Find the constant of proportionality. R is inversely proportional to the square of I. If I=25, then R=100.arrow_forwardLeaf blower the intensity of the sound from a certain leaf blower is measured at 3.2102W/m2 .find the describe 1level .arrow_forwardSolve each problem. w is directly proportional to z.
