Planck Length

The Planck length is the smallest meaningful unit of length in physics, representing a fundamental scale at which classical ideas about gravity and space-time break down and quantum effects dominate.

• 
  

  It is defined as approximately 1.616 × 10⁻³⁵ meters.

  
  
• 
  

  The Planck length is derived from fundamental constants: the speed of light, Planck’s constant, and the gravitational constant.

  
  
• 
  

  It sets a theoretical limit below which the very concepts of space and distance may lose conventional meaning.

  
  
• 
  

  Used mainly in theories of quantum gravity and string theory.

  
  

Key facts:

• 
  

  1 Planck length ≈ 1.616 × 10⁻³⁵ m

  
  
• 
  

  Smallest scale in quantum physics and cosmology

  
  
• 
  

  Represents a scale where quantum effects of gravity become significant

  
  

The Planck length is crucial for understanding the fabric of the universe at its most fundamental level.

Ångström

An ångström (symbol: Å) is a unit of length commonly used in physics, chemistry, and biology to measure very small distances, such as atomic and molecular scales. It is equal to 10⁻¹⁰ meters, or 0.1 nanometers (nm).

The unit is named after the Swedish physicist Anders Jonas Ångström, who made significant contributions to spectroscopy.

Key facts:

• 
  

  1 ångström = 10⁻¹⁰ meters = 0.1 nanometers

  
  
• 
  

  Used to measure atomic and molecular sizes, wavelengths of light, and crystal lattice constants

  
  
• 
  

  Common in fields like crystallography, chemistry, and materials science

  
  

Though largely replaced by the nanometer in the SI system, the ångström remains widely used in scientific literature to describe very small lengths.
