Ozone reflects _ radiation from sun back into space.
Correct answer: B. UV
- A. IR
- B. UV
- C. Alpha
- D. All of these
Explanation
Ozone is known for its ability to absorb and scatter ultraviolet radiation from the sun. In the Earth's atmosphere, the ozone layer absorbs a significant portion of the incoming UV radiation, particularly UV-B and UV-C, protecting life on Earth from harmful effects of excessive UV exposure. Therefore, ozone primarily reflects UV radiation back into space.OPTIONS A & C: Ozone doesn't reflect or absorb IV and Alpha radiation hence these options are incorrect.

About Alternating Current
Alternating current varies periodically, so phase relationships become essential when current passes through a resistor, capacitor or inductor. The chapter distinguishes resistance from capacitive and inductive reactance, explains phase lead and lag, and connects changing electric and magnetic fields with the production and properties of electromagnetic waves.
