Duality Of light

2.

States:

The idea that light is a wave motion
Light will go in every direction from a light source
Light spreads throughout the medium

3.

Huygens Principle each point on the leading surface of a wave disturbance may be regarded as a secondary source of spherical waves, which themselves progress with the speed of light in the medium and whose envelope at later times constitutes the new wave front

Wave Theory Allowed

4.

Newton came up with this theory

Light is made of small particles
Photons obey same laws of physics for masses
Photons are so small that when two particle beams intersect they dont rebound off of each other

Later Max Planck said that particles have some wave like properties

6. This explains the wave-particle duality 7. Stating that light acts like waves in propagation, interference, and diffraction 8. But like particles when reacting with matter 9. Because of Planck quantum mechanics was createdParticle Theory Continued

10. Plancks Constant

Planck's constant = 6.626068 10-34 m2 kg / s = h

11. Plancks constant was the result of experimentation
