Newton and HookeLight Issues

• Photons

2

• In this lecture we hope to convince you all that
  both Hooke and Newton had valid hypothesis.
• Based on recent discoveries and their original
  experiments we can confirm that both had key
  roles in the development of knowledge about
  light.
• In their lifetimes both disputed the others
  theories and conclusions. However today we can
  make our own conclusions based on both of their
  theories.

Nature of Light

• Newton Light is composed of particles.
• (Corpuscular)
• Hooke Light is composed of waves.
• (Undulating)
• Dual Nature of Light.

4
Dispersion of Light

• Newton White light is composed of other colours.
• Hooke White is a fundamental colour. Other
  colours are only an effect of disturbance.
• (Red and Blue light have different speeds.)
• Complete theory of dispersion.

Vibration of Light

• Newton Light is composed of particles receptors
  in eyes vibrate.
• Hooke Light is produced by an exceedingly
  quick vibration of the material.
• Light vibrates travels across vacuum and
  materials.

Conclusions

• By looking at the work of both Robert Hooke and
  Isaac Newton it is possible to have a greater
  understanding of the topic of light.
• Their experiments were made in different contexts
  and with different variables.
• As a result we believe in both theories. If you
  take a laser there is no wave. Make a hole in
  paper, smaller than the laser beam, the laser
  will travel in the same way through the
  paper(smaller beam).
• With a lamp and two holes, the light will travel
  through in the same way but with an interference.
  This proves that light is a wave.

Dialogue

• Newton I think that Newtons theory of light is
  correct because of the fact that when you put
  white light through a prism it divides into seven
  colours and when you put another prism at one of
  the colours it doesnt change.
• Hooke white light is uncompounded and colours
  are produced when white light is disturbed by
  refraction. it is only the impression of our
  retina.
• Newton Your explanation is incorrect because
  light is a vibration of the sensors on your
  retina.
• Hooke In is not the retina but the material
  which the light passes through which vibrates.
• Newton How do you explain the stright line
  movement of the particles?
• Hooke It is a short quick vibration (waves)
  rather than particles.
• Newton Perhaps we both have correct ideas, we
  should collaborate to find out more.

• We believe that light particles move in waves
