How long would gamma radiation take to travel from Sun to Earth a distance of?
} {\rm{s}}}\] for v in equation (1) to get the value of time taken by gamma radiation to reach earth starting from the sun. {\vphantom {{\rm{m}} {\rm{s}}}} \right. Therefore, the time taken by gamma radiation to travel from the sun to earth is equal to \[500{\rm{ s}}\].
How far do gamma waves travel?
If the narrowly directed beam happens to be pointed toward the Earth, it shines at gamma ray frequencies with such intensity, that it can be detected even at distances of up to 10 billion light years, which is close to the edge of the visible universe.
What happens when gamma radiation occurs?
Gamma rays are a radiation hazard for the entire body. They can easily penetrate barriers that can stop alpha and beta particles, such as skin and clothing. Gamma rays can pass completely through the human body; as they pass through, they can cause ionizations that damage tissue and DNA.
How long light takes from Sun to Earth?
The Sun is 93 million miles away, so sunlight takes 8 and 1/3 minutes to get to us.
What would a gamma-ray burst do to life on Earth?
“A gamma-ray burst originating within 6,000 light years from Earth would have a devastating effect on life,” said Dr. Adrian Melott of the Department of Physics and Astronomy at the University of Kansas. “We don’t know exactly when one came, but we’re rather sure it did come — and left its mark.
How rare are gamma ray bursts in the Milky Way galaxy?
Gamma-ray bursts in our Milky Way galaxy are indeed rare, but the scientists estimate that at least one nearby likely hit the Earth in the past billion years. Life on Earth is thought to have appeared at least 3.5 billion years ago.
How dangerous are gamma rays to humans?
These are among the most deadly radiation known. If a person happened to be near a gamma-ray producing object, they’d be fried in an instant. Certainly, a gamma-ray burst could affect life’s DNA, causing genetic damage long after the burst is over.
When was the gamma ray discovered?
It was first discovered by a French chemist and physicist, Paul Villard in 1900. It was named gamma ray by Ernest Rutherford in 1903. Gamma rays are ionizing in nature, which means that they are capable enough to release electrons from atoms.
