Answer 1

The three types of waves that can be harmful to life are:

1. **Ultraviolet rays** - Excessive exposure to UV rays can lead to skin cancer, cataracts, and other health issues.

2. **Gamma rays** - These are highly energetic waves that can cause significant damage to living tissues and DNA, increasing the risk of cancer and other health problems.

3. **X-rays** - While they are used in medical imaging, prolonged or excessive exposure to X-rays can also lead to cellular damage and increase cancer risk.

Infrared rays, microwaves, radio waves, and visible light are generally not harmful in typical exposure conditions.
