A large hall in a museum has a niche in one wall. On the floor plan, the niche appears as a semicircular indentation of radius 3.85 m. A tourist stands on the centerline of the niche, 3.30 m out from its deepest point, and whispers "Hello." Where is the sound concentrated after reflection from the niche? m from the deepest point in the niche Need Help? Read It
= The figure is shown TO SCALE. Each block represents a 1.00 cm square. It shows a ray of light entering a rectangular piece of glass (n₂ 1.50) from air (n₁ = 1.00). Find the position (x,y in cm) where the ray exits the glass. Or, if it does not exit the glass, find the (x,y) position of the second point (the second reflection) where total internal reflection occurs. In either case, be sure to check if total internal reflection occurs. Cheese file to unload Movimuvo filo cine: 20MDY
