A layer in the Earth's atmosphere called Ionosphere facilitates radio communication. Why? 1. The presence of ozone causes the reflection of radio waves to Earth. 2. Radio waves have a very long wavelength. Which of the statements given above is/are correct?

1. Statement 1 is incorrect: The reflection or refraction of radio waves back to Earth by the Ionosphere is due to the presence of free electrons and ions, created by solar radiation ionizing atmospheric gases. Ozone, primarily found in the stratosphere, is mainly involved in absorbing UV radiation and does not cause the reflection of radio waves. 2. Statement 2 is incorrect: While the interaction between radio waves and the Ionosphere depends on the wave's frequency (and thus wavelength), stating they have a "very long wavelength" is not the primary reason for the facilitation of radio communication. Specific frequency ranges (like shortwave) are reflected/refracted effectively by the ionospheric layers. The key factor is the ionized nature of the layer interacting with waves of suitable frequencies, not simply the wavelength being 'very long'.
