The layer in the Earth's atmosphere which reflects radio waves from the Earth, thus helping radio communication is

Options

  1. Astratosphere
  2. Bmesosphere
  3. Ctroposphere
  4. Dionosphere

Correct answer

D. ionosphere

Step-by-step solution

Ionosphere is the ionised part of Earth's atmosphere, which reflects the radiowaves due to total internal reflection towards earth, thus it helps in radio communication.
