The following are the optical properties of three materials A,B and C.
Property A B C
reflectivity 0.85 0.15 0.001
Absorptivity 0.1 0.7 0.1
a) Determine the transmissivity of the materials
b) which material heats up fastest when illuminated?
c) which one will be the most transparent and which one the least?
d) which material will shine most when illuminated?
a. Transmittance = I/Io
b. the least reflective
c. the least absorbance
d. the most reflective.
