2. Aborption Light is absorbed while propagating through glass
alpha is the absorbtion coefficient.
x is the thinkness of the glass.

3. S-Wave and P-Wave
The component of the electric field parallel to plane of incidence is termed p-like (parallel) and the component perpendicular to this plane is termed s-like (from senkrecht, German for perpendicular).
Polarized light with its electric field along the plane of incidence is thus denoted p-polarized, while light whose electric field is normal to the plane of incidence is called s-polarized.

5. Reflectance Reflectance coefficient (right angle): For n = 1.5 R = 4%
Note: If we use 4 uncoated lenses:
T = (0.96)*(0.96)*(0.96)*(0.96) = 0.85.
