COSMIC RAYS
- 1. COSMIC RAYS PREPARED BY TOSIF AHMAD M.SC PHYSICS SECOND YEAR PRESENTATION ON
- 2. WE WILL DISCUSS • WHAT ARE COSMIC RAYS • DISCOVERY OF COSMIC RAYS • TYPES OF COSMIC RAYS • EFFECT OF COSMIC RAYS
- 3. • Charged particles (protons, electrons, and other atomic nuclei) coming from outer space. • Traveling at near the speed of light, 186,000 miles per second, or 300,000 km per second. What are Cosmic Rays?
- 4. What are Cosmic Rays? High speed protons and electrons, primary particles, strike Earth’s upper atmosphere. Nuclear collisions produce a shower of secondary particles, called muons. It is mainly these muons that are observed on Earth’s surface.
- 5. . . Discovery of Cosmic Rays • From 1911 to 1913 Victor Hess measured radiation levels at various altitudes (up to 17,500 ft) in the Earth’s atmosphere. • Radiation levels increased with altitude! • This radiation was called “Cosmic Radiation” later became “Cosmic Rays”. • Won Nobel Prize in 1936.
- 6. TYPES OF COSMIC RAYS • 1) PRIMARY COSMIC RAYS • 2) SECONDARY COSMIC RAYS ( COSMIC SHOWER )
- 8. EFFECT OF COSMIC RAYS • COSMIC RAYS HAVE ALSO RISKS FOR THE MANNED SPACE FLIGHT BETWEEN PLANETS • COSMIC RAYS PENETRATE INTO THE EARTH FROM ANY DIRECTION OF SPACE • COSMIC RAYS HAVE SUCH AGREAT ENERGY THAT THEY MIGHT DAMAGE THE OBJECT THEY CAN CHANGE THE SITUATION OF ELECTRICAL INTRIGATED CIRCUITS.
- 9. EFFECT OF COSMIC RAYS • THEY CAUSE ERROR IN MEMORY CARDS AND THEY DAMAGE MICRO ELECTRONIC CHIPS AND CIRCUITS • THEY PERTICULARLY DETERIORATE THE LIVES OF THE PEOPLE LIVING ATHIGH ALTITUDES
