This led Max Planck to develop the theory of quantum mechanics, which accurately predicted the observed radiation spectrum by introducing the concept of quantized energy. | Fadhel Mahdi | Facebook

Think thinner fabric means less UV protection? 🤔 Let's test that idea in the next episode of our "UV Myths, Busted" video series! Featuring the UNIQLO Pocketable UV Protection Parka - it's lightweight, breathable and still offers UPF50 protection — the maximum rating for UV protective clothing. And tested under the harsh Australian sun ☀️ #UniqloAU #LifeWear #SportUtilityWear #SUW *Ultraviolet Protection Factor (UPF) measures the amount of UV radiation that can penetrate fabric and reach your s
