Is a gamma ray a natural ray?

Yes, gamma rays are a type of natural radiation that are generated by radioactive materials or processes such as nuclear fission. They have the shortest wavelength and highest frequency among electromagnetic waves, and can be emitted from sources like stars, supernovae, and radioactive decay.

What kingdom do stingrays belong?

Most people would consider fish in the Animalia kingdom ( animal kingdom ), Fish, mammals, insects, animals of course would all belong to the Animalia kingdom. Unlike us we belong to god. But if you are Muslim or Islam or even Jewish and Sikh you would know what kingdom you belong to. -Top Contributor Hillary

Compare and contrast x rays and gamma rays?

X-rays and gamma rays are both forms of electromagnetic radiation, but differ in their origins. X-rays are typically produced by accelerated electrons hitting a target, while gamma rays originate from nuclear processes like radioactive decay or nuclear reactions. Gamma rays have higher energy and penetrating power compared to X-rays, making them more harmful to living organisms.

Why are refracted rays smaller that incident rays?

Refraction occurs when light waves pass from one medium to another at an angle, causing a change in their speed and direction. The change in speed causes the refracted rays to bend towards the normal line, making them appear smaller in comparison to the incident rays. This bending is a result of the change in speed and wavelength of the light waves as they travel through different mediums.

What is the Difference between neutron and gamma rays?

Neutrons are neutral particles found in the nucleus of an atom, while gamma rays are electromagnetic radiation emitted by the nucleus of an atom. Neutrons have mass but no charge, while gamma rays are massless and have no charge. Neutrons are typically involved in nuclear reactions, while gamma rays are involved in the release of excess energy from an unstable nucleus.

How do string rays get food?

Stingrays primarily feed on mollusks, crustaceans, and small fish. They use their electroreceptors, located on their rostrum, to detect prey that is buried in the sand or hidden in the water. Once they locate food, they use their flattened teeth to crush and eat it.

How does the manta ray conserve energy?

Manta rays conserve energy by gliding effortlessly through the water using their large pectoral fins. They also move with the ocean currents to reduce the amount of energy needed for swimming. Additionally, manta rays have a cartilaginous skeleton, which is lighter and more flexible than a bony skeleton, helping them to maneuver with less effort.

What are some kinds of rays you have heard of?

Some types of rays include manta rays, stingrays, and electric rays. Manta rays are large, graceful creatures found in the ocean, while stingrays are known for their venomous barbs. Electric rays can produce electric shocks to defend themselves or hunt for prey.

How strong is the stingray?

Stingrays are not particularly strong swimmers in terms of speed but they are strong in the sense that they have powerful tails and can deliver a painful sting with their barb if threatened.

Is there a ray with shorter wavelength than the gamma ray?

Cosmic rays have shorter wavelength than gamma rays

Are rays posinous?

No, rays are not poisonous. However, some ray species have venomous spines that can cause painful stings if they come into contact with a person. It's important to be cautious when handling rays to avoid getting stung.

What is the relation between incident ray and emergent ray?

The incident ray is the ray of light that first strikes the surface of a medium or interface, while the emergent ray is the ray of light that exits the medium after being refracted or reflected. The direction of the emergent ray depends on the angle of incidence and the properties of the medium.

What do uv rays penetrate?

UV rays can penetrate through the Earth's atmosphere and reach the surface of the skin, causing damage such as sunburn and skin cancer. They can also penetrate through clouds and glass, so it's important to protect the skin by wearing sunscreen and protective clothing when exposed to sunlight.

Is a stingray fast or slow?

Stingrays are generally considered to be slow swimmers, capable of moving at a moderate pace while gliding through the water. They are not known for their speed or agility compared to other marine animals like dolphins or sharks.

How does being flat on the bottom help the stingray?

Being flat on the bottom helps stingrays camouflage themselves against the ocean floor, making them less visible to predators and allowing them to ambush prey more effectively. It also helps them conserve energy by minimizing effort when gliding along the seabed. Additionally, their flattened shape enables efficient water flow over their bodies, aiding in propulsion and maneuverability.

What do gamma rays look like?

Gamma rays are a form of electromagnetic radiation that are not visible to the human eye. They have the shortest wavelengths and highest frequencies in the electromagnetic spectrum. While gamma rays cannot be seen, they can be detected using specialized instruments like gamma-ray detectors.

How do Manta Rays fly through water?

The gill slits of the manta ray are visible on its ventral side. It respires like fish do, taking in water through its mouth and then letting it pass over its gills and then exit through the gill slits. Use the link to the Wikipedia article and check out the pictures. Or use the other link to a picture posted at Geocities showing a 5,000 pound creature taken from the ocean.

How do humans use infared rays?

Humans use infrared rays in various ways, such as in thermal imaging cameras to detect heat signatures, in remote controls to operate electronic devices, and in infrared saunas for therapeutic purposes. Infrared rays are also used in security systems for motion detection and in cooking appliances for faster and more even cooking.

How do you get gamma rays?

Orign of Gamma Rays

Gamma rays are part of the electromagnetic radiation spectrum. Electromagnetic Radiation is VERY basically energy travelling in waves. One source of electromagnetic radiation is our sun. The reason why Gamma Rays do not hit the earth, is because the earth is protected by an MAGNETIC field. The Earth's core is Iron, and Iron is magnetic, so this field sheilds us from the harmful radiation, and is one of the reasons why life exists on the earth today. Light is also radiation, so it's important to note that not all radiation is actually bad for living Organisms. Gamma rays are sometimes used in Medical treatment to kill of cancer cells, (Chemotherapy.)

Also another source of Gamma Rays are unstable elements of the periodic table that give off Electromagnetic Radiation.... such as Uranium,Plutonium and so on.

How many volts does a stingray give off?

A stingray can give off up to 220 volts when it delivers an electric shock as a defense mechanism.

Can a stingray electrocute you?

Stingrays do not possess the ability to produce electricity and therefore cannot electrocute you intentionally. However, some species of stingrays have electrical organs that can produce a mild electric shock for self-defense if they feel threatened or agitated.

Does a stingray move fast or slow?

Like most animals, a stingray can move either way. It will move slowly when it is feeding or just swimming around, and it will move fast if it is in danger.

Are alpha rays neutrons?

Alpha particles are helium nuclei -- each particle is composed of two protons and two neutrons. A stream of alpha particles may be called a ray, although as it is not electromagnetic radiation that is probably inaccurate.
