In a thin film interference, what type of interference occurs when light reflect

In a thin film interference, what type of interference occurs when light reflects off a medium with a higher refractive index?

In a thin film interference, what type of interference occurs when light reflects off a medium with a higher refractive index?

Step 1: Understand that light can reflect off surfaces.
Step 2: Know that when light reflects off a medium with a higher refractive index, it undergoes a phase change.
Step 3: Recognize that this phase change is π (which is equivalent to 180 degrees).
Step 4: Learn that this phase change can lead to destructive interference when the light waves combine.
Step 5: Conclude that the type of interference that occurs in this situation is destructive interference.
