What property of this wave is represented by the letter "A"

• amplitude
• crest
• trough
• wavelength

Tags

NGSS.HS-PS4-1

The highest point on a wave is:

• the crest
• the trough
• the top
• the coast

NGSS.MS-PS4-1

The lowest point on a wave is the:

• Amplitude
• Crest
• Trough
• Wavelength

Wavelength and Frequency are related in that...

• they are always the same

• when one increases, the other decreases (inversely proportional)

• there is no correlation

• they both vary in an irregular pattern
