Apparent magnitude is a logarithmic scale used in astronomy to measure the brightness of celestial objects as seen from Earth. It depends on the object’s size, distance, and frequency of light emitted. Absolute magnitude is a measure of an object’s actual brightness, taking into account its distance. The scale is historical, with lower values indicating […]
Magnitude scales are used to measure the strength of earthquakes and the brightness of stars. The astronomical magnitude scale measures the amount of light emitted by stars, with higher numbers indicating fainter stars. The Richter scale measures the energy released by an earthquake, with each unit representing ten times more energy. The moment magnitude scale […]
