Which part of the electromagnetic spectrum is the most dangerous & harmful?
Which part of the electromagnetic spectrum is the most dangerous & harmful?
Gamma rays
Gamma rays are the most energetic and extremely dangerous form of the electromagnetic waves.
What wavelength is harmful to humans?
The most significant adverse health effects have been reported at wavelengths below 315 nm, known collectively as actinic ultraviolet.
What part of the electromagnetic spectrum is most dangerous to humans Why?
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.
Which part of the electromagnetic spectrum can cause damage?
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….The three main types of ultraviolet radiation and some of their effects.
| Type | Frequency | Hazard |
|---|---|---|
| UVC | High | Causes severe damage to cells |
Which of the following wavelengths is most damaging to living cells?
Ultraviolet radiation (UVR) is the portion of solar radiation with wavelengths of 200-400 nm (nanometers). Radiation of these short wavelengths vibrates at very high frequency and is powerful enough to damage living cells and tissues.
Which part of the EM spectrum is visible to humans?
visible light spectrum
The visible light spectrum is the segment of the electromagnetic spectrum that the human eye can view. More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 nanometers.
What wave has the longest wavelength?
Radio waves
Nearly all frequencies and wavelengths of electromagnetic radiation can be used for spectroscopy. Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation. Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.
What is the wavelength of the visible spectrum for electromagnetic radiation?
The visible wavelengths cover a range from approximately 0.4 to 0.7 µm. The longest visible wavelength is red and the shortest is violet.
