Why does white light split into different colors when it passes through a prism?

<p>Because each color is refracted differently, each bends at a different angle, resulting in a fanning out and separation of white light into the colors of the spectrum</p> Signup and view all the answers

How can you split white light?

<p>Position your white light source above or around the prism to point towards one of its faces. Turn on the light and observe how the beam refracts off of each face as it passes through, dispersing into its component colors.</p> Signup and view all the answers

Study Notes

Wave Properties

  • Amplitude: Height of a wave
  • Wavelength: Distance between two corresponding parts of a wave
  • Period: Time to complete one wave cycle
  • Frequency: Number of waves passing a point per second
  • Speed of a wave: Calculated as speed = distance/time or speed = frequency × wavelength
  • Energy Transfer: Waves transfer energy

Wave Interactions

  • Transmission: Light passing through matter
  • Absorption: Light taken in by matter
  • Reflection: Light bouncing off a surface
  • Refraction: Light deflected from a straight path

Applications of Waves

  • Ultrasound: Used for medical imaging, automatic door openers, animal communication, and sonar
  • Seismic Waves: P and S waves create shadow zones, regions where these waves cannot be detected

Wave Types

  • Transverse Waves: Particles move perpendicular to wave direction (e.g., light waves, some seismic waves)
  • Longitudinal Waves: Particles move parallel to wave direction (e.g., sound waves, some seismic waves, ultrasound)

Light Dispersion

  • White light splitting: Different colors refract at different angles, separating white light into the spectrum of colors
  • Refraction and Prisms: Prisms are used to separate white light into its colors through refraction
  • Incident angle: Angle between incident ray and normal to the surface
  • Incident ray: Ray of light striking a surface
  • Reflected ray: Ray of light bouncing off a surface
  • Reflected angle: Angle between reflected ray and normal to the surface
