Objectives of the GACE Physics: Waves, Sound & Light Chapter

The topics in this chapter will confirm and enhance your existing knowledge as well as introduce you new or unfamiliar concepts that will be tested on the GACE Physics assessments. Both Test I and II will assess your understanding of 6-12th grade level physics in order to determine your ability and eligibility to teach middle or high school science courses in the state of Georgia.

Your knowledge of sound and light waves will be tested in the Optics and Waves subarea (32% of Test II). The self-assessment quizzes provided at the end of each lesson will test your comprehension of the information covered on the exam and also give you insight to the types of questions you'll encounter on test day.

Vibrations and Waves: Energy and Motion

1. Vibrations and Waves: Energy and Motion

When an object is manifesting a repetitive motion over the same path in a rhythmic way, it is vibrating, which means waves are being formed. Learn about vibrations and waves, amplitude and energy.

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

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

Wave parameters refer to the different ways waves are measured. Examine how waves are characterized by wavelength, amplitude, period, frequency, and/or speed.

Transverse & Longitudinal Waves: Definition & Examples

3. Transverse & Longitudinal Waves: Definition & Examples

In transverse waves, particles of a medium move perpendicular to the wave's direction of travel and in longitudinal waves, the particles move parallel. Explore the definition and examples of these waves, how they travel through solids, liquids, and gasses, and learn about seismic waves.

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

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

Sound is a longitudinal wave that travels through various states of matter, like solids, and not through a vacuum. Discover the definition and factors affecting the speed of sound including nature of sound waves, mediums, and the wave equation.

Pitch and Volume in Sound Waves

5. Pitch and Volume in Sound Waves

In sound waves, pitch is the frequency of sound and volume is the intensity of sound. Explore the parameters of sound, the definitions of amplitude, intensity, and frequency, and the acoustic range.

Electromagnetic Waves: Definition, Sources & Properties

6. Electromagnetic Waves: Definition, Sources & Properties

Electromagnetic waves are both electric and magnetic, and can travel without a medium. Learn about the definition, sources, and properties of electromagnetic waves.

The 7 Major Regions of the Electromagnetic Spectrum

7. The 7 Major Regions of the Electromagnetic Spectrum

Unlike some other waves, electromagnetic waves don't require a medium to travel. This lesson delves into the frequencies of the electromagnetic spectrum including infrared, ultraviolet, microwaves, X-rays, radio waves, and gamma rays.

The Nature of Light: Origin, Spectrum & Color Frequency

8. The Nature of Light: Origin, Spectrum & Color Frequency

The nature of light includes visible light and color. Explore the origin, spectrum, and color frequency of light and learn about the six color ranges and people's perception and naming of color.

Reflection: Angle of Incidence and Curved Surfaces

9. Reflection: Angle of Incidence and Curved Surfaces

The reflection of waves occurs when a wave changes direction after it hits a surface. Explore incident and reflected rays, the law of reflection, and reflection off curved surfaces.

Diffuse Reflection: Definition, Examples & Surfaces

10. Diffuse Reflection: Definition, Examples & Surfaces

When rays hit a rough surface, their reflections go in diverse directions. This phenomenon is called diffuse reflection. Learn its definition, its difference from specular reflection, and different examples of diffuse reflection in sound and light waves.

Resonance: Definition & Transmission of Waves

11. Resonance: Definition & Transmission of Waves

Resonance is when the amplitude of an object's oscillations is increased by the matching vibrations of another object. Explore the definition, transmission of waves, resonate frequency, and resonance in music.

Transparent and Opaque Materials in Electromagnetic Waves

12. Transparent and Opaque Materials in Electromagnetic Waves

Transparency and opacity describe interactions in regions throughout the electromagnetic spectrum. Explore the differences between transparent and opaque materials, their relation to transmission and reflection, and non-visible wave types.

Color: White Light, Reflection & Absorption

13. Color: White Light, Reflection & Absorption

When you perceive color, what you're really seeing is how white light is reflected or absorbed by an object to produce different visible light frequencies. This lesson investigates the properties of white light, the color spectrum, the process of selective absorption and reflection, and how pigments work in living things.

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

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

When a light wave passes from one medium into another, it changes direction in a process called refraction. This lesson investigates the properties of refraction, including the index of refraction and the ratio known as Snell's Law.

Diffraction: Relation to Sound & Light and Effects of Wavelength

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

Diffraction describes a unique behavior of waves where they bend as they travel through certain mediums. Explore the diffraction of sound and light, and the effects of wavelength on diffraction.

Constructive and Destructive Interference

16. Constructive and Destructive Interference

When two waves meet while traveling in the same medium, they disrupt each other in a process called interference, which produces an entirely new wave. Discover the two types of interference, constructive and destructive, and learn how a single wave can interfere with itself.

The Doppler Effect: Definition, Examples & Applications

17. The Doppler Effect: Definition, Examples & Applications

The Doppler effect explains why a sound's pitch seems to change depending on whether it's coming towards you or moving away from you. This lesson investigates how the Doppler effect works, and how it can be applied to the behavior of both sound waves and light waves.

Wave-Particle Duality: Concept, Explanation & Examples

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

When the photoelectric effect was discovered, it challenged the preconceived scientific theory that science that light behaves like a wave. This lesson explores how light can act as both a wave and a particle, and how this discovery led to the theory of wave-particle duality.
