Young's experiment and the dual nature of lightFeatured science projectScience project video
Light has a dual nature: it has the characteristics of both waveforms and particles. This science project was conducted in order to help us better understand the dual nature of light. This paper explains the double split experiment which is also known as Young's experiment, and how the experiment demonstrates the waveform nature of light.
Hypothesis

The double slit experiment will prove that light has the properties of waveforms.

Overview

Dual nature of light

Light has the ability to demonstrate the behavior of both particles and waveform. The double split experiment, also known as Young’s experiment, demonstrates the wave-like behavior of light: where interference of light causes the formation of light and dark lines on a screen. Also, the particle properties of light can be demonstrated through photons. This wave-particle dual nature of light is studied under the field of quantum mechanics.

The waveform behavior of light enables us to understand the different colors of light around us. Electromagnetic rays from the sun consist of waveforms that have different frequencies and wavelengths. Each band of frequency in the visible light spectrum is seen as a different color.

Light is also known to exist as photon particles. These particles do not have a mass, are without electric charge and do not decay. Photons are carriers of electromagnetic force and are able to demonstrate the properties of both waves and particles.
