Question asked by Filo student
Reflection and Refraction of Light - Page 5 Physics 7C The formulas governing this are: Unless an object is completely opaque, some light will pass through and some will be reflected. 1- ncosθ R= n1cosθ + ncosθ (3) ncosθ T=1-R (4) Here, R is the fraction of light reflected and T is the fraction transmitted. 7. If light reflects from all surfaces, why is the view through a glass window (nglas = 1.5) not noticeably dimmer than the view with the window open? Do the calculation to support your answer.

Question Text | Reflection and Refraction of Light - Page 5 Physics 7C
The formulas governing this are:
Unless an object is completely opaque, some light will pass through and some will be reflected.
1- ncosθ
R= n1cosθ + ncosθ (3)
ncosθ
T=1-R (4)
Here, R is the fraction of light reflected and T is the fraction transmitted.
7. If light reflects from all surfaces, why is the view through a glass window (nglas = 1.5) not noticeably dimmer than the view with the window open? Do the calculation to support your answer. |
