At the Science Lab, the students should state the effects of different EM waves in our environment.
What are the effects of different EM waves in our environment?
Ma'am, I choose Radio waves. Radio waves can warm up the tissues. They are due to absorption of energy from the radio waves into the body.
GoodAnyone else?
Ma'am, I choose Microwaves. Microwaves can heat body tissue. Higher levels and long exposure can lead to skin burn.
Ma'am, I choose Infrared. Infrared waves can cause eye damage, skin damage and also involved in greenhouse effect.
Ma'am, I choose X-Ray. X-Ray is electromagnetic radiation of extremely short wavelength. The ionizing radiations penetrate the living tissues and can destroy living cells, chromosomal aberrations and carcinogenic effect
Ma'am, I choose Gamma-rays. Gamma-rays from space are absorbed by Earth's atmosphere. They can destroy living cells, produce mutations, and cause cancer.
Very Good you guys. I'm really happy because you understand today's lecture and you even know what are the effects of the different EM waves.
