Ch.2 Sect.1 - Waves and the Electromagnetic Spectrum

Waves that require a medium to travel through

• Mechanical waves

• Electromagnetic waves

• Light waves

• Radio waves

A disturbance that transfers energy from place to place, without permanently disturbing the substance.

• Wave

• Crest

• Trough

• Amplitude

Which of these is NOT one of the four properties of waves?

• Wavelength

• Amplitude

• Vibration

• Speed

NGSS.HS-PS4-1

Complete waves passing by a point each second and measured in Hertz (Hz)

• Wavelength

• Amplitude

• Frequency

• Speed

How far the wave travels in a given amount of time. It can be found by multiplying its frequency by its wavelength.
