Physical Science Waves

Which of these describes ALL waves?

• energy that moves from side to side.

• energy that moves in a regular pattern.

What happens when waves move across the surface of deep water?

• The water moves up and down.

• The water does not move.

When does water move in the direction of a wave?

• When boats move through the water.

• When the water gets close to the beach.

What is amplitude?

• the distance from the middle point of a wave to the wavelength.

• the distance between the middle point of a wave and a crest or trough.

Look at the photo. It shows the waves that formed when a small rock was dropped into the water. The waves are not very tall nor far apart. Which of the following correct describes the properties of these waves?

• High amplitudes and long wavelengths.

• Low amplitudes and short wavelengths.

Which of these waves would transfer the MOST energy?

• One with a low crest.

• One with a high amplitude.

What is a wavelength?

• The distance from one crest to the next crest or one trough to the next trough.

• The distance from a crest to a trough.

Which part of the drawing is a wave trough?

• 1

• 2

What does it mean if waves have short wavelengths?

• The distance from one trough to the next is small.

• The distance from on crest to the next trough is large.

Which of these is an example of transmitting information with digital code?

• sending a text on a cell phone

• using Morse code
