Are electromagnetic waves beneficial or harmful explain?

Evidence for cellular effects of electromagnetic fields. The general opinion is that there is no direct evidence of hazardous effects on human health incurred by low-frequency radiofrequency waves. Studies at the cellular level, which uses relatively higher frequencies, demonstrate undesirable effects (10-11).

Are electromagnetic waves beneficial?

EMR has very beneficial uses of our daily life to make it more comfortable and easier. Nowadays, we can talk to anyone on a mobile phone through the Internet: it is because of EMR, since these waves can transmit signals for very long distanc- es. So EMR has the key roles in making our lives more comfortable.

What makes electromagnetic waves beneficial?

Radio waves are transmitted easily through air. They do not cause damage if absorbed by the human body, and they can be reflected and refracted to change their direction. These properties make them ideal for communications.

Can electromagnetic waves be harmful?

Over-exposure to certain types of electromagnetic radiation can be harmful. The higher the frequency of the radiation, the more damage it is likely to cause to the body: infrared radiation is felt as heat and causes skin to burn.

How does electromagnetic radiation affect living things?

Lesson Summary 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.

How Can radiation be harmful and helpful?

Ionizing radiation can affect the atoms in living things, so it poses a health risk by damaging tissue and DNA in genes. has sufficient energy to affect the atoms in living cells and thereby damage their genetic material (DNA). Fortunately, the cells in our bodies are extremely efficient at repairing this damage.

Is electromagnetic radiation is beneficial or harmful to the environment and the living things?

For example, high energy microwave radiation at frequencies from 300 MHz to 300 GHz can be carcinogenic and cause thermal effects, increasing the temperature of exposed organisms. The opinions of researchers about the influence of electromagnetic pollution on living organisms are divided.
