Wave-Particle Duality: Concept, Explanation & Examples

1. Wave-Particle Duality: Concept, Explanation & Examples

Is light a particle with mass and substance? Or, is it just a wave traveling through space? Most scientists say light is both a particle and a wave! Find out how they came to this strange conclusion as we learn about the theory of wave-particle duality.

Constructive and Destructive Interference

2. Constructive and Destructive Interference

What happens when one wave meets another? Do the waves converge to make one giant wave? Or, do they destroy each other? In this lesson, we'll explore the workings of wave interference.

Diffraction: Relation to Sound & Light and Effects of Wavelength

3. Diffraction: Relation to Sound & Light and Effects of Wavelength

This lesson explores diffraction as one of the many behaviors of waves. Learn how diffraction occurs in sound and light waves and how it is affected by the wavelength of a wave. Find out how animals use diffraction to communicate and how scientists use it to study molecules.

Refraction & Dispersion: Definition, Snell's Law & Index of Refraction

4. Refraction & Dispersion: Definition, Snell's Law & Index of Refraction

Refraction explains why light bends in water. But, did you know that mathematical laws determine exactly how light waves are bent? In this lesson, we'll explore the mechanics of wave refraction, including Snell's Law and the index of refraction.

Color: White Light, Reflection & Absorption

5. Color: White Light, Reflection & Absorption

What gives color to objects? How do light waves interact with materials to produce red and green or white and black? In this lesson, learn how white light is composed of all colors and how absorption and reflection influence our color perception.

The Doppler Effect: Definition, Examples & Applications

6. The Doppler Effect: Definition, Examples & Applications

What is the Doppler effect? How does it affect our perceptions of sound and light? In this lesson, learn how traveling wave sources can change the way we observe sound and light waves. Explore the applications of the Doppler effect on shock waves, sonic booms, and the movements of distant galaxies.

Pitch and Volume in Sound Waves

7. Pitch and Volume in Sound Waves

What do pitch and volume mean when talking about sound waves? Further your understanding of sound waves in this lesson as we explore the more familiar aspects of sound. We'll learn about pitch and volume and how they relate to sound wave parameters.

What is Sound? - Definition and Factors Affecting the Speed of Sound

8. What is Sound? - Definition and Factors Affecting the Speed of Sound

Explore the minute workings of sound waves and how they travel. We'll discuss the main factors that affect the speed of sound waves, and we'll try some mathematical problems involving the wave equation.

Transverse & Longitudinal Waves: Definition & Examples

9. Transverse & Longitudinal Waves: Definition & Examples

What comes to mind when you think of a wave? Chances are your mental image takes the form of a transverse wave. But, longitudinal waves are just as important, and understanding the difference is vital to learning about waves. In this lesson, explore both types of waves and the unique characteristics of each.

Wave Parameters: Wavelength, Amplitude, Period, Frequency & Speed

10. Wave Parameters: Wavelength, Amplitude, Period, Frequency & Speed

How do we measure and describe waves? How do waves differ based upon their shapes? This lesson will guide you through the five wave parameters - period, frequency, amplitude, wavelength, and speed - that we use to characterize waves.

Vibrations and Waves: Energy and Motion

11. Vibrations and Waves: Energy and Motion

What is a wave? What causes waves, and how do they travel from one place to another? This lesson will guide you through the basics of waves. We'll discuss their origins from vibrations and investigate how they carry energy through a medium.
