Riding the Waves of Information Study Guide

The highest point of a wave is the

• wavelength

• trough

• crest

What machine is used to send a message in Morse code?

• telephone

• telegraph

• telestudent

What is NET MOTION?

• The average height of a wave

• The average change in position of an object

• the distance an object travels

• the distance between one crest and the next one

What is amplitude?

• The height of a wave from the baseline to the crest

• the height of a wave from the bottom, or trough, to the top, or crest

• the highest part at the top

• the distance from one crest to the next

How is a wave or a vibration started?

• energy

• distance

• matter

How do I measure the wavelength of a wave?

• find the distance of all the crests

• find the distance from the trough to the baseline

• find the distance from one trough to the next trough

• find the distance from the crest to the next trough

What do waves carry?

• matter

• energy

• objects
