Study Notes
Measurement of Sea Depth
- The depth of the sea is typically measured in meters (m) or feet (ft).
- Bathymetry is the study of underwater depth of ocean floors, using sonar technology for accurate measurements.
Atom Bomb Principle
- An atom bomb operates on the principle of nuclear fission.
- During fission, heavy atomic nuclei such as uranium-235 or plutonium-239 split into smaller nuclei, releasing huge amounts of energy.
Correction of Astigmatism
- Astigmatism is commonly corrected using cylindrical lenses in eyeglasses or contact lenses.
- Corrective lenses help to refocus light correctly onto the retina, improving vision clarity.
Equal Temperature of Fahrenheit and Centigrade
- The Fahrenheit and Celsius (Centigrade) scales equal each other at -40 degrees.
- This unique point is the temperature at which both temperature scales converge.
Energy Conversion in Batteries
- In batteries, chemical energy is converted into electrical energy.
- This conversion occurs through electrochemical reactions generating electric current to power devices.
