The straw appears bent in the liquid. This is because the light rays leaving the straw change direction when they hit the surface between the liquid and the air.

  • Light travels  at  different speed in different mediume
  •  The wavelengths of the primary colour interfear with each other to toghether to show different colours 
  • The eye contains nerves that identify 3 colours

    Light and other types of electromagnetic radiation are transverse waves. Water waves and S waves (a type of seismic wave) are also transverse waves. In transverse waves, the vibrations are at right angles to the direction of travel.
    - example:  vibrations in strings, ripples on water surface and electromagnetic waves]]>     2018-05-16 10:10:40 UTC https://padlet.com/nika_vugrinec/85id03uozfpw/wish/261152159     Longitude waves nika_vugrinec https://padlet.com/nika_vugrinec/85id03uozfpw/wish/261152319 Longitudinal waves are waves in which the displacement of the medium is in the same direction as, or the opposite direction to, the direction of propagation of the wave. ... Transverse mechanicalwaves are also called "shear waves".
    example: Longitudinal waves include sound waves(vibrations in pressure, particle of displacement, and particle velocity propagated in an elastic medium) ]]>     2018-05-16 10:11:07 UTC https://padlet.com/nika_vugrinec/85id03uozfpw/wish/261152319     diagram nika_vugrinec https://padlet.com/nika_vugrinec/85id03uozfpw/wish/261152467 2018-05-16 10:11:50 UTC https://padlet.com/nika_vugrinec/85id03uozfpw/wish/261152467 What is the red shift nika_vugrinec https://padlet.com/nika_vugrinec/85id03uozfpw/wish/262180340 the displacement of spectral lines towards longer wavelengths (the red end of the spectrum) in radiation from distant galaxies and celestial objects. This is interpreted as a Doppler shift which is proportional to the velocity of recession and thus to distance.
