Which type of radiation has the shortest wavelength?
Gamma RaysGamma Rays-have the smallest wavelengths and the most energy of any other wave in the electromagnetic spectrum.
These waves are generated by radioactive atoms and in nuclear explosions..
Are short or long wavelengths more dangerous?
In general, the shorter the wavelength, the greater the danger to living things. Although longer wavelengths also have their hazards, very short wavelengths, such as X-rays and gamma rays, can easily damage living tissue.
What is the shortest wavelength of visible light?
VioletWAVELENGTHS OF VISIBLE LIGHT As the full spectrum of visible light travels through a prism, the wavelengths separate into the colors of the rainbow because each color is a different wavelength. Violet has the shortest wavelength, at around 380 nanometers, and red has the longest wavelength, at around 700 nanometers.
What are the 7 types of waves?
Though the sciences generally classify EM waves into seven basic types, all are manifestations of the same phenomenon.Radio Waves: Instant Communication. … Microwaves: Data and Heat. … Infrared Waves: Invisible Heat. … Visible Light Rays. … Ultraviolet Waves: Energetic Light. … X-rays: Penetrating Radiation. … Gamma Rays: Nuclear Energy.
What is the weakest wave?
The Electromagnetic spectrum lists the most powerful EMR, gamma rays, to the least powerful EMR, radio waves. In addition, the highest energy waves (gamma, x-ray) have the shortest wavelengths. The lowest energy waves, radio waves, have longest wavelengths.
What frequency is dangerous to humans?
Scientific evidence suggests that cancer is not only linked to mobile phone radiation and that other factors also may be involved in its development. Most mobile operators use from radiofrequency waves in the range up 300 MHz to 3 GHz that can be harmful for human health (1).
What color has lowest frequency?
redWhen it comes to visible light, the highest frequency color, which is violet, also has the most energy. The lowest frequency of visible light, which is red, has the least energy.
What is the weakest form of electromagnetic radiation?
Radio wavesRadio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation. In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves.
What color is lowest in energy?
RedThe frequency of the radiation is proportional to its energy and the wavelength of the radiation is inversely proportional to the energy. Red is the lowest energy visible light and violet is the highest. A solid object has color depending on the light it reflects.
Why can humans only see visible light?
The reason that the human eye can see the spectrum is because those specific wavelengths stimulate the retina in the human eye. … If we move beyond the visible light region toward longer wavelengths, we enter the infrared region; if we move toward shorter wavelengths, we enter the ultraviolet region.
Why is red light better than violet light?
Violet light has the shortest wavelengths so the violet light’s peaks encounter the glass first and are bent first. The red light has the longest wavelengths so the crests or peaks encounter the glass last and are the last to be bent.
