Why are some electromagnetic waves harmful?

Over-exposure to certain types of electromagnetic radiation can be harmful. … infrared radiation is felt as heat and causes skin to burn. X-rays damage cells causing mutations (which may lead to cancer) and cell death – this is why doctors and dentists stand behind protective screens when taking lots of X-rays.

Why are some electromagnetic waves harmful and others not?

because the speed of all electromagnetic waves are the same, wavelength decreases while frequency increases. The shorter the wavelength, the higher the frequency. … Why are some electromagnetic waves harmful to you but others are not? the high frequencies and shorter wavelengths penetrates body easily.

Why do electromagnetic waves become harmful?

At low frequencies, external electric and magnetic fields induce small circulating currents within the body. … The main effect of radiofrequency electromagnetic fields is heating of body tissues. There is no doubt that short-term exposure to very high levels of electromagnetic fields can be harmful to health.

Which electromagnetic waves are harmful?

The most dangerous frequencies of electromagnetic energy are X-rays, gamma rays, ultraviolet light and microwaves. X-rays, gamma rays and UV light can damage living tissues, and microwaves can cook them.

Why are high frequency electromagnetic waves harmful?

It has been known for many years that exposure to very high levels of RF radiation can be harmful due to the ability of RF energy to heat biological tissue rapidly. … Exposure to very high RF intensities can result in heating of biological tissue and an increase in body temperature.

What are the uses and dangers of electromagnetic radiation?

Properties, Dangers and Uses

How does the electromagnetic waves destroy and effect the living tissues?

Some forms of electromagnetic radiation, which is radiation found in different kinds of light waves, including ultraviolet light and X-rays, can cause damage to the DNA inside a living cell. When DNA is damaged by radiation, it can lead to cell death or to cancer.

What are some harmful effects of radiation on humans and the environment?

Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness”). It can also result in long-term health effects such as cancer and cardiovascular disease.

How do EM waves affect our lives?

Explanation: Electromagnetic Radiation is a spectrum that can be anything from Radio Waves to Gamma Rays. We use visible light to see, radio waves to send information, microwaves to heat food, infrared for sensors, UV damages our skin and is used in black lights, X-rays let us see bones, and Gamma Rays damage our body.
