LIGHT SCATTERING

• light scattering depends on the size of particles.

  small amount of particles = short wavelengths

  large amount = longer wavelengths
• the most scattered color in the atmosphere is violet followed by blue and green
• red light has the least amount of scattering because it has the longest wavelength.
• Rayleigh scattering depends on the relative size of

  the particles and the wavelength of light.

  ● Mie scattering refers to the scattering of mostly

  white light and depends less on the wavelength.

  A) rayleigh

  B) mie

  
• diffraction is the spreading of light when encounters an opening
• diffraction depends on the opening of an obstacle

  
  

  smaller opening = greater diffraction

  greater opening = smaller diffraction
• interference is the combination of two or more waves that meets on the same point
• destructive interference is when the two waves having opposite direction meets. it cancels the movement.
• constructive interference is when the two identical waves meet. it results a new wave with the same wavelength but doubled amplitude.
• diffraction yarn

  
• bright lights means constructive and the dark ones mean destructive
