Two students
demonstrated the use of a pyranometer
in class to measure the short-wave radiation outside (e.g. the
short-wave
radiation emitted from the Sun) and in front of the overhead projector
(e.g.
the short-wave radiation emitted from the light bulb). They measured
16.1 mV
(millivolts) outside, and 5.0 mV in front of the overhead projector.
Their
pyranometer had a calibration of 62.3 .
Use their data to answer the next two questions.

D.
78.4
E.
1003.0
12.

from the
light bulb in the overhead projector?
A.
0.08
B.
21.1
C.
57.3
D.
67.3
E.
311.5
