Question

station 3
which layer contains charged particles that can affect radio signals?
a. troposphere
b. stratosphere
c. exosphere
d. ionosphere

Explanation:

The ionosphere contains a high - density of charged particles (ions and free electrons). These charged particles can reflect, refract, and absorb radio waves, thus affecting radio signals. The other layers (troposphere, stratosphere, exosphere) do not have such a significant effect on radio signals due to the lack of a high concentration of charged particles.

Answer:

D. Ionosphere
