Worked Solution & Example Answer:A wave travels across the surface of water - AQA - A-Level Physics - Question 15 - 2020 - Paper 1
Step 1
Which row correctly describes both $w$ and $z$?
Answer
To determine the correct descriptions of and , we refer to the characteristics of wave properties illustrated in the diagram:
-
Understanding : The variable refers to the maximum displacement of water particles from their rest position, which is defined as the amplitude of the wave.
-
Understanding : The variable represents the distance between successive peaks of the wave. This distance is known as the wavelength.
Therefore, the correct descriptions are:
- is the amplitude.
- is the wavelength.
From the options provided, the correct row is A: amplitude and wavelength.
