Question

What is reflectivity, absorpinay, and transmissivig? How are they related to each other? Include a picture and an equation in youresplanation for full credit.

Answer 1

Step-by-step explanation:

Lets take G is the incident radiation on the body.

`G=G_a+G_r+G_t`

Where

`G_a`absorptive part of G

`G_r` reflected part of G

`G_t`transmitted part of G

lets take a is the absorptivity ,r is the reflectivity and t is the transmissivity.

So
`G_a=a G,G_r=r G,G_t=t G`

G=a G+r G+t G

So We can say that

1=a+r+t

We can say that

absorptivity is the capacity of a body to absorb the incident radiation.

reflectivity is the capacity of a body to reflect the incident radiation.

transmissivity is the capacity of a body to transmit the incident radiation.
