Reading a Wave

Name the parts of a wave off the picture, then get speed, wavelength and frequency out of it.

7 questions, free, marked as you go with a worked explanation on every one.

What this covers

• wave speed and period

The questions

1. On the wave drawn, which measurement is taken from the rest position out to a crest?
2. Which distance on the drawing is exactly one wavelength?
3. The graph shows the shape of a wave along a rope, measured in centimetres. What is its wavelength?
4. A wave on that rope has a wavelength of 4 cm and a frequency of 25 Hz. What is its speed?
5. You are shaking the rope to make the wave drawn. What would halve its wavelength?
6. Which of these are true of the wave drawn?
7. A sound wave travels at 340 m/s with a frequency of 170 Hz. What is its wavelength?
