わんこのお散歩あるある〜！まるも下水溝の金網のフタとかグレーチングっていう格子柄のあみあみが怖い派なんだけど、なんでかわかる？それはね、わんこには穴に見えるときがあるからなんだ～。ほら、わんこってあんまり視力がよくないからねえ。あるいはね、肉球のすき間に網の部分が食い込んで痛い思いをした経験があるからなの。避けて通る理由、わかると簡単でしょう？だから無理やり引っ張って通らそうとしないでね。わんこの体を張ったアピールに気づいてほしいの。ちなみに、安全だと気づいたらまるだってへっちゃらな金網あるよ。 As is often the case with dogs, they dislike walking on a grating. Do you want to know why? Because they think it as a hole or they have a pain in their paw pad. So treat them with consideration and do not pull really hard on the leash. #動物愛護週間 #あみあみ恐怖症 #網目は苦手

這是有一次 跟物理迷因 @physical_daily_meme 聊到的有趣現象 當時覺得太有趣，就決定撰寫了 ٩۹(๑•̀ω•́ ๑)۶ 另外泡泡與汽油 應為薄膜造成的#干涉現象 光碟與孔雀則為#繞射現象。 這部分容易搞混， 所以在這裡附註說明。 而他們都屬於虹彩現象。 至於其他種類的虹彩現象 其原因我一時間查不到原理不敢亂寫。 如果讀者知道的話 歡迎告訴我，我會補充在這裡。 (≧ω≦)/  「註」： 有些文章會用反射等等字眼 我想是為了幫助容易了解。 實際上blazed grating 造成的繞射現象在光學教科書裡 有很深的探討但我們多數人用不到， 所以這裡簡單提及而已     reference: Lawrence T.
