Ответ:
When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases. Part of the wave travels faster for longer causing the wave to turn. The wave is slower but the wavelength is shorter meaning frequency remains the same

Area of the triangle is 10,000 km²
Step-by-step explanation:
Step 1: Find the area of the triangle with base = 200 km and height = 100 kmArea of the triangle = 1/2 × base × height
= 1/2 × 200 × 100 = 10,000 km²
