Photons cause electrons to move to excited state.
In excited state in the conduction band, electrons are free to move through the material.
This motion of the electron creates an electric current in the cell.
But how far can electrons move? And because electrons are free to move in...
Thank you for your reply. I tried to understand better how the prisms work and also to learn more about the refractive index
You say:to avoid 100% reflection is to have a substance with higher refractive index than air behind the face (changing the critical angle).
But there is the other glass...
Thank you for the reply.
You say:

By FACE do you mean the place where the blue ray enters the prism( here, in the picture, it is the top) ?
@sophiecentaur: Thank you for your explanation.
In your first reply from Aug7-14, 10:06 PM, you pointed out I forgot the blue ray from the mirror will go back out of the top face.
Do you think that will distort the picture( makes it less significant)?
Thanks
Thank you for your replies.
@Lok: Can you please explain a little more what you mean by:the bottom image exits mirrored while the top one does not
Thanks
Thank you both of you for the replies.
@Lok
How should l use of the beam splitter? (One ray enters and two rays go out in 90°).
But I need two images ( one up, one down i.e. 180° between them) to be seen together .
I also found this solution
The black lines are the mirrors. The red...
I use right angle prisms to make an image alignment.
Let's suppose 1st and 2nd image are the same. The 1st image should be aligned with the 2nd image.
My problem is that right angle prism deviates input ray about 8°. ( Prisms are made of bk7 material which has refractive index = 1.5168 )...
