What are the 7 types of rays?
Answer: The 7 electromagnetic waves in order are Radio Waves, Microwaves, Infrared Radiation, Visible Light, Ultraviolet Radiation, X-Rays, and Gamma Rays. The electromagnetic spectrum comprises seven types of waves, each with unique characteristics and applications. Microwaves are widely used in modern technology, for example in point-to-point communication links, wireless networks, microwave radio relay networks, radar, satellite and spacecraft communication, medical diathermy and cancer treatment, remote sensing, radio astronomy, particle accelerators, spectroscopy, industrial .Microwaves are a form of electromagnetic radiation; that is, they are waves of electrical and magnetic energy moving together through space. Electromagnetic radiation spans a broad spectrum from very long radio waves to very short gamma rays.
What are the four types of rays?
There are four major types of radiation: alpha, beta, neutrons, and electromagnetic waves such as gamma rays. They differ in mass, energy and how deeply they penetrate people and objects. Types of radiation differ in their ability to penetrate material and damage tissue, with alpha particles the least penetrating but potentially most damaging and gamma rays the most penetrating.Inside the body, however, they can be very harmful. If alpha-emitters are inhaled, swallowed, or get into the body through a cut, the alpha particles can damage sensitive living tissue. The way these large, heavy particles cause damage makes them more dangerous than other types of radiation.Gamma rays may pass all the way through a human body without striking anything. They are considered to have the least ionizing power and the greatest penetration power. A comparison of Alpha particles, beta particles and gamma rays is given in Table 11.Gamma rays have tremendous penetration power and require several inches of dense material (like lead) to shield them. Gamma rays may pass all the way through a human body without striking anything. They are considered to have the least ionizing power and the greatest penetration power.
What are alpha and beta rays?
Gamma rays are neutral, while alpha particles have a positive charge and beta particles have a negative charge. Two protons and two neutrons are bound together to form an alpha particle. High-energy electrons are known as beta particles. Gamma rays are photons, which are electromagnetic energy waves. An alpha-particle is identical to the nucleus of a normal (atomic mass four) helium atom i. Alpha particles (also termed alpha radiation or alpha rays) was the first nuclear radiation to be discovered, beta particles and gamma rays were identified soon after.Alpha particles have approximately four times the mass of a proton or neutron and approximately ~8,000 times the mass of a beta particle (Figure 5. Because of the large mass of the alpha particle, it has the highest ionizing power and the greatest ability to damage tissue.Alpha rays are positively charged particles. Alpha-particle is a highly active and energetic helium atom that contains two neutrons and protons.Alpha particles weigh 4 atomic mass units, making them the heaviest of the common decay particles. Thus, they have the lowest velocities and largest impulses relative to beta and gamma particles. Further, their +2 charge gives alpha particles the strongest Coulombic force.
