The light  reflected from the back surface (side of angle of incidence) will travel farther than the light reflected from the front surface.

What is reflection of light?

Reflection of light is the ability of light to bounce back when it strikes a smooth surface.

For a surface of a given thickness, the speed of the light will decrease once it strikes such surface.

n1sin(Фi) = n2sin(Фr)

where;

  • Фi is the incident angle
  • Фr is the angle of refraction

Thus, for a film of thickness d, and incident angle of 90 degrees, the light  reflected from the back surface (side of angle of incidence) will travel farther than the light reflected from the front surface.
