Question 1112535: The percent of light p, as a decimal, that passes through a substance of thickness d, in meters, is given by log (p)=−kd. The value of k for this particular type of opaque glass is 6. How thick should a piece of this glass should be, so that only 20% of the light passes through it?

log (p) = -kd
:
log (0.20) = -6d
:
d = -log (0.20) / 6 = 0.1165
:
The glass should have a thickness of 0.1165 meters
