| 説明 | When it comes to beautiful blue the Pipevine has it. This blue is only visible at the right angle and light. In thin film interference color is generated by a process of selective wave cancellation. Because light travels different distances when it reflects off of layers at different depths, the emerging waves vary depending on the angle. Notice how the blue in this angle has a green hint. That is the iridescent effect where changing the angle causes different waves to cancel out. The waves that remain are more green than blue. |
