1. The Speed & Nature of light

2. What is light? Light is a form of electromagnetic radiation.
Light is made up of waves of tiny bundles of energy call photons

3. A photon is the carrier of electromagnetic radiation of all wavelengths
It is a weightless
Particle that acts like
A wave.
A photon is a bundle of electromagnetic energy.

4. A photon is a bundle of electromagnetic energy
A photon is a bundle of electromagnetic energy. Waves of light create rays and bundles of rays make beams.

5. Electromagnetic radiation waves come in many forms.
Infrared waves
Visible light radiation
(This what we call Light)
Microwaves
Ultra-violet
radiation
Radio waves
X-rays

6. 300,000 kilometers/seconds (in vacuum)
All of types of electromagnetic radiation share one similarity between them:
They all travel at the same speed of light 186,000 miles/seconds (in vacuum) Or
300,000 kilometers/seconds (in vacuum)
(in vacuum) through air and space.

7. When light slows down or changes direction we see refraction of light
Examples of refraction:

8. The speed of light depends on what it is traveling through.
In water, light slows down to about 200,000 km/seconds

9. Refraction through water

10. Examples of refraction:

11. Following are examples of artists
M.C. Escher and Salvador Dali who
were inspired by and included
Refraction and Reflection in their art
