Consider the following statements: I. In the Earth's atmosphere, shorter wavelengths such as blue light undergo stronger scattering than longer wavelengths such as red light. II. Clouds appear white because water droplets scatter the different wavelengths of visible light in a broadly uniform manner. III. To an astronaut observing from beyond the Kármán line, the sky would appear red. How many of the above statements are correct?
