प्लैंक लंबाई (Planck length) भौतिकी में लंबाई की एक मौलिक इकाई है। प्लैंक लंबाई को अक्सर दूरी की सबसे छोटी सार्थक इकाई के रूप में वर्णित किया जाता है। यह प्रकाश की गति, गुरुत्वाकर्षण स्थिरांक और प्लैंक स्थिरांक जैसे मौलिक स्थिरांकों को मिलाकर प्राप्त किया जाता है। प्लैंक लंबाई उन पैमानों को चिह्नित करता है […]

क्या है आयरन डोम (What is Iron Dome) ?
आयरन डोम (Iron Dome) इजराइल की एक वायु रक्षा प्रणाली है। यह हवा में ही 4 से 70 किलोमीटर के दायरे में दुश्मन की मिसाइलों को रोकने और नष्ट करने की क्षमता रखता है। इसे राफेल एडवांस्ड डिफेंस सिस्टम्स और इज़राइल एयरोस्पेस इंडस्ट्रीज द्वारा बनाया गया है। हाल ही में हुए ईरानी सुपरसोनिक मिसाइल हमलों […]
When is a Nuclear Reactor called Critical?
When Nuclear fuel sustains the fission chain reaction inside a nuclear reactor, the reactor is said to be critical. In this, the amount of neutrons produced by nuclear fission becomes equal to or greater than the number of neutrons produced by the nuclear material. Nuclear fuel maintains the fission chain reaction, or criticality, during normal […]
The Comprehensive Nuclear Test Ban Treaty (CTBT)
The Comprehensive Nuclear Test Ban Treaty (CTBT) is an important multinational treaty that aims to ban all nuclear explosions, whether for military or civilian purposes. It began in the Cold War era when the United States and the Soviet Union conducted nuclear weapons and intensive tests. The end of the Cold War and the dissolution […]
India’s Chandrayaan-3
The successful soft landing of India’s Chandrayaan-3 near the Moon’s south pole on August 23, 2023 was a historic moment. This feat made India the first country to achieve the remarkable feat of landing a spacecraft so close to the south pole of the Moon. Chandrayaan-3, India’s third lunar mission and second attempt at a […]
What is The Kármán Line ?
The Kármán Line, located 100 kilometers above sea level, serves as an imaginary boundary between the Earth’s atmosphere and outer space. Although scientists and astronauts disagree, most nations and space organizations recognize this limit as a viable limit. The Fédération Aéronautique Internationale (FAI) established the Kármán Line in the 1960s, and anyone crossing it is […]
Marine Cloud Brightening: A Promising Solution for Climate Mitigation
Marine cloud brightening (MCB) is a concept developed by British cloud physicist John Latham in the 1990s. The primary goal of the MCB is to fight global warming by altering the Earth’s energy balance by increasing cloud brightness. This cutting-edge technology aims to mitigate the consequences of climate change by increasing reflectivity and deflecting more […]
Isotopes of Hydrogen and its uses
Hydrogen has three isotopes: protium (1H), deuterium (2H), and tritium (3H). Protium is the most common isotope and has no neutrons, deuterium has one neutron, and tritium has two neutrons. इस टॉपिक से संबंधित टेस्ट Details about the isotopes of hydrogen : These isotopes of hydrogen play an important role in various scientific and industrial […]
Why is Saturn’s status as a giant planet in question ?
Saturn is a large planet with a mass of about 100 times that of Earth. Despite this, Saturn is still about three times smaller than Jupiter. Some astronomers have begun to question how Saturn really fits into being classified as a large planet in light of this and more recent discoveries. Saturn and Jupiter are […]
Transverse Waves and its Examples
If the particles oscillate perpendicular to the direction of wave propagation, then it is a transverse wave. In plain words, the motion of the constituent particles of the medium or wave is perpendicular to the path of propagation of the wave. Transverse waves include the following examples: About the Author Manish love to write and […]
