This is because water has different absorption capabilities for different colors of light. Water molecules have a stronger absorption capability for red and blue light, while their absorption capability for green light is relatively weaker.\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cbr\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0994\/9338\/0395\/files\/SD15.webp?v=1778655437\" alt=\"\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0994\/9338\/0395\/files\/SD16.webp?v=1778655443\" alt=\"\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0994\/9338\/0395\/files\/SD17.webp?v=1778655448\" alt=\"\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0994\/9338\/0395\/files\/SD18.webp?v=1778655454\" alt=\"\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0994\/9338\/0395\/files\/XTAR-SD151.webp?v=1778655460\" alt=\"\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0994\/9338\/0395\/files\/SD110.webp?v=1778655466\" alt=\"\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0994\/9338\/0395\/files\/SD11_9c2575b5-6d81-4590-b668-78594d83be4d.webp?v=1778655468\" alt=\"\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0994\/9338\/0395\/files\/SD12.webp?v=1778655475\" alt=\"\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0994\/9338\/0395\/files\/SD13.webp?v=1778655480\" alt=\"\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0994\/9338\/0395\/files\/SD116340-900-1.webp?v=1778655485\" alt=\"\"\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"ShenZhen XTAR Electronics Co., Ltd","offers":[{"title":"China \/ SD1 KT(No Battery)","offer_id":53369580618027,"sku":"AF058003","price":19.9,"currency_code":"USD","in_stock":true},{"title":"China \/ SD1 SET (With 16340 650mAh Battery)","offer_id":53369580650795,"sku":"AF058005","price":25.5,"currency_code":"USD","in_stock":true},{"title":"China \/ SD1 SET (With 16340 900mAh USB-C Battery)","offer_id":53369580683563,"sku":"AF058017","price":25.8,"currency_code":"USD","in_stock":true},{"title":"USA \/ SD1 SET (With 16340 650mAh Battery)","offer_id":53369580716331,"sku":"SD1 SET (Protected 16340)","price":27.5,"currency_code":"USD","in_stock":true},{"title":"USA \/ SD1 SET (With 16340 900mAh USB-C Battery)","offer_id":53369580749099,"sku":"SD1+16340 USB-C SET","price":27.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/9338\/0395\/files\/6e139a31a3.jpg?v=1777649028","url":"https:\/\/xtardirect.com\/products\/xtar-sd1-diving-flashlight","provider":"XTAR Official Store","version":"1.0","type":"link"}
