Question

which of these correctly shows types of radiation increasing in energy? microwaves → tv waves → x - rays → cosmic rays tv waves → microwaves → cosmic rays → x - rays tv waves → microwaves → x - rays → cosmic rays cosmic rays → x - rays → microwaves → tv waves

Explanation:

Step1: Recall the energy order of radiation

The energy of electromagnetic radiation increases as the frequency increases. The order of increasing energy (and frequency) for common radiations is: TV waves (lowest energy) < microwaves < X - rays < cosmic rays (highest energy).

Step2: Check each option

• Option 1: Microwaves → TV Waves → X - rays → Cosmic rays. This is incorrect because TV waves have lower energy than microwaves.
• Option 2: TV Waves → Microwaves → Cosmic rays → X - rays. This is incorrect because X - rays have higher energy than cosmic rays.
• Option 3: TV Waves → Microwaves → X - rays → Cosmic rays. This follows the correct order of increasing energy.
• Option 4: Cosmic rays → X - rays → Microwaves → TV Waves. This is in the order of decreasing energy.

Answer:

TV Waves → Microwaves → X - rays → Cosmic rays (the third option)
