Answers with explanation
1)
Transmission
If all the light passes through a medium without any absorption then transmittance is 100%.
2)
Refraction
Refraction is the bending of a wave when it enters a medium where its speed is different and rays are again refracted when they leave that medium,
3)
Reflection
Reflected rays don't pass through the medium instead rays bounces off an object at an angle.
0.12244898 is the value obtained when solving the given.
<u>Explanation:</u>
Given:
3 times 10 to the 8th power can be expressed in equation format as
(3 times symbolizes ‘multiplication’ then it is to the tenth power of 8)
2.45 times 10 to the 9th power can be expressed in equation format as
(2.45 times symbolizes ‘multiplication’, then it is to the tenth power of 9)
Asked to find the solution when dividing the above,
![\frac{3 \times 10^{8}}{2.45 \times 10^{9}}=\frac{3}{2.45} \times 10^{8-9}](https://tex.z-dn.net/?f=%5Cfrac%7B3%20%5Ctimes%2010%5E%7B8%7D%7D%7B2.45%20%5Ctimes%2010%5E%7B9%7D%7D%3D%5Cfrac%7B3%7D%7B2.45%7D%20%5Ctimes%2010%5E%7B8-9%7D)
When the tenth power of any value goes from denominator to numerator and vice-versa, presents in opposite sign to that it possess (like when ‘
' goes to numerator changed as '
').
Now by solving the above equation, we get
![\frac{3}{2.45} \times 10^{8-9}=1.22 \times 10^{-1}=\frac{1.22}{10}=0.12244898](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2.45%7D%20%5Ctimes%2010%5E%7B8-9%7D%3D1.22%20%5Ctimes%2010%5E%7B-1%7D%3D%5Cfrac%7B1.22%7D%7B10%7D%3D0.12244898)
