Waves in Action

The video tutorial explains the characteristics of waves, focusing on wavelength and amplitude. It includes activities to draw waves on paper and create a wave model using a rope. The tutorial also poses questions to help understand how wave properties are affected by different factors.

What is the distance between two consecutive crests of a wave called?

• Velocity

• Wavelength

• Frequency

• Amplitude

In the wave drawing activity, what tool is used to ensure the lines are straight?

• Protractor

• Eraser

• Ruler

• Compass

How can you increase the wavelength of a wave in the drawing activity?

• Draw the dots closer together

• Draw the dots further apart

• Use a thicker pencil

• Make the lines darker

When using a rope to model a wave, what happens to the wavelength if you shake the rope more vigorously?

• The wavelength decreases

• The wavelength increases

• The wavelength remains the same

• The wavelength becomes zero

Which factor is most likely to affect the amplitude of ocean waves?

• The temperature of the water

• The color of the water

• The depth of the ocean

• The wind speed
