What is the different between stage drama and radio drama?

Stage drama is performed live in front of an audience, relying on physical presence, visual elements, and stagecraft to convey the story. In contrast, radio drama is an audio-only medium that uses sound effects, dialogue, and music to create an immersive experience without visual components. While stage drama emphasizes performance and visual storytelling, radio drama focuses on auditory techniques to engage listeners' imaginations. Both forms share narrative elements but differ significantly in execution and audience interaction.
