There are many different types of waves. (a) Waves on the surface of water are transverse waves. Sound waves are longitudinal waves. Describe the difference between transverse waves and longitudinal waves. (iii) A student uses the image to estimate the speed of the water wave as 75 cm/s. Which of these is a reason why the estimate is not correct? A the student used a ruler without mm markings B the light was not bright enough C the student's measurement was inaccurate D the wave seen on the screen is magnified

Answer

Transverse waves have oscillations that are perpendicular to the direction of wave travel. In contrast, longitudinal waves have oscillations that occur in the same direction as the wave travels.

Step 2

Which of these is a reason why the estimate is not correct?

Answer

The most likely reason the estimate is not correct is option A: the student used a ruler without mm markings. This could lead to inaccuracies in the measurement of the wave speed.
