glass beaker 3d model

A sharp photorealistic scientific illustration of light refraction in a transparent glass beaker filled with clear water. A straight transparent glass rod inserted diagonally into the water appears bent at the air-water interface due to refraction. Show a red incident light ray entering from air and bending inside the water as a refracted ray. Include a dashed vertical normal line at the water surface, with labeled angles θ₁ and θ₂ between the rays and the normal. Minimal clean white background, realistic reflections, transparent glass texture, studio lighting, educational physics diagram style, ultra detailed, high resolution.”
