Fundamental Theories of Light

And
then
God
Said
Let there be Light.
History
3
But for those scientist out therehere are some
scientific theories that were developed over time.
4
The Theory of Light
Particle
Emissions
Tactile
Wave
Quantum
5
What is the...
Tactile Theory
Invisible probes are sent out by the eye to
feel objects
6
Strengths
Weaknesses
Doesnt explain anything about light and makes
very little sense.
It was the first theory of light that was
developed.
7
Emissions Theory
Contradicted the Tactile Theory
Bright and shiny send out beams that ricochets
off other objects and then enter the human eye.
8
Strength
Weakness
Single rays can not be polarized.
This was accepted over the tactile.
Cant see in the dark
9
Particle Theory
Does Light Travel In Straight Lines?
10
This Theory was developed by Sir Isaac
Newton.
This system of particles are emitted in all
directions from a source in straight lines.
11
Weaknesses
Strengths
Does not support polarizing and interference with
other particles. Also this can not be proven when
speed is high or size is small.
Supports how light reflects and how light travels
in a straight line.
12
Wave Theory
Huyens Theory
Light as a Wave
13
Strengths
Polarizing can take place
Matter is not needed to transmit light
Weaknesses
The inability to bend around corners
14
EINSTEINS
Quantum Theory
15
Plank first discovered this theory in 1887
Light transmitted and absorbed in small bundles
of energy.
These were called quanta and are equal to the
frequency of light.
Einstein developed it
16
Weaknesses
Strength
Combined many other theories to get this one. The
latest theory found.
Can not be found
17
MY THEORY
My theory is light is light. Its there because
its suppose to be just like the grass and the
sky. I am a simple person but if I had to agree
with a theory it would most likely be the quantum
theory. It makes the most sense.
