Their product is the constant c , the speed of light, which is equal to 3.00 × 10 8 m/s . This relationship reflects an important fact: all electromagnetic radiation, regardless of wavelength or frequency, …

Overview of key terms and skills for waves, including how to identify longitudinal and transverse waves.

When a wave interacts with an object it can be transmitted through the object. This depends on the object's material and the frequency of the wave. Light waves journey from the sun, through space …

Usually, waves travel in a straight line until they interact with a boundary. Refraction happens when a wave’s path bends at a boundary as it transmits into a new medium. The amount a wave refracts …

Review your understanding of mechanical waves and light in this free article aligned to NGSS standards.

Transverse and longitudinal waves are two types of mechanical waves, which involve the transfer of energy through a medium (e.g. water, air, a solid). Learn about transverse and longitudinal waves …

Review the characteristics of periodic transverse and longitudinal waves such as wavelength, crest, trough, amplitude, expansion, and compression.

Use a simulation to explore waves. Learn about the wave properties of frequency, wavelength, speed, and amplitude.

Electromagnetic waves Explore the properties and behaviors of electromagnetic waves, focusing on visible light. Examine how frequency and amplitude determine color and brightness, and learn how …

Learn about electromagnetic waves, including visible light waves. Explore the ray model and use it to model different behaviors of light.
