What is the medium of light? Let's see. ✨🔦

6/10 Edited to

... Read moreจากประสบการณ์การเรียนวิทยาศาสตร์และการสอนพิเศษ ตัวกลางของแสงจริงๆ มีบทบาทสำคัญอย่างมากในการส่งผ่านพลังงานแสงจากแหล่งกำเนิดไปยังดวงตาหรือวัตถุต่างๆ ผมมักจะใช้ตัวอย่างในการอธิบายเพื่อให้เข้าใจได้ง่าย เช่น ในตัวกลางโปร่งใสอย่างแก้วใส หรืออากาศ แสงสามารถผ่านไปได้โดยไม่เกิดการเบี่ยงเบนมากนัก ทำให้เรามองเห็นภาพชัดเจน อย่างเช่นเมื่อเรามองผ่านหน้าต่างที่ทำจากแก้วใส ในทางกลับกัน ตัวกลางโปร่งแสง เช่น กระจกฝ้าหรือผ้าบางๆ จะทำให้แสงผ่านได้บางส่วนแต่กระจัดกระจายไป ทำให้ภาพที่เรามองผ่านไม่ชัดเจน เหมือนการมองผ่านผ้าม่านบางๆ ที่ยังไม่มืดสนิท แต่ก็มองเห็นลางๆ ตัวกลางทึบแสง เช่น ไม้ เหล็ก หรือผนังคอนกรีต จะไม่ยอมให้แสงผ่านเลย จึงทำให้เกิดเงามืดข้างหลังวัตถุนั้น ผมใช้สิ่งนี้อธิบายเรื่องเงาที่เกิดจากวัตถุในชีวิตประจำวัน การเข้าใจความแตกต่างของตัวกลางเหล่านี้ไม่เพียงแต่ช่วยในการเรียนรู้วิทยาศาสตร์เท่านั้น แต่ยังมีประโยชน์ในการประยุกต์ใช้ในชีวิตจริง เช่น การเลือกวัสดุกันแดด หรือการจัดแสงในห้องเรียน เพื่อให้แสงผ่านได้เหมาะสมที่สุด หวังว่าการสรุปและแบ่งปันนี้จะช่วยให้ทุกคนเข้าใจเรื่องตัวกลางของแสงได้ชัดเจนและนำไปใช้ในการเรียนหรือชีวิตประจำวันได้ดีขึ้นค่ะ

75Medium rules (January 22- April 7)
Okay, I been seeing 75hard all over social media & finally I decided to do it my self. Never give up. Never surrender. You can do anything if you just put your mind to it. 75hard - seems a little hard for me. I can’t do 2 workouts per day, working full time job. But 75medium seems great

Let’s talk shrinkage!✨
I prevent shrinkage by twisting my hair when it’s semi dry. Example: I wash and condition my hair, section it and put big twists in my hair overnight. The next day, my hair is partially dry, little damp, I twist my hair for styling (referring to picture 2). I take my twists out, separate my curls,
