Exploring the Shape of Light Waves

The video explains different types of waves, including ocean, seismic, sound, and light waves. It describes wave properties such as amplitude, wavelength, and frequency, and how these properties affect sound and light. Sound waves with different frequencies and amplitudes produce varying pitches and volumes, while light waves with different wavelengths and frequencies result in different types of light. The video concludes with a summary of how waves carry energy and interact with materials.

Which of the following is NOT a type of wave mentioned in the video?

• Seismic waves

• Sound waves

• Microwave waves

• Light waves
