Try this first
In a stationary wave formed on a string, what is the distance between two consecutive nodes?.
- A.Half the wavelength
- B.The wavelength
- C.Twice the wavelength
- D.One quarter of the wavelength
Model answer
What a good answer should say
- Half the wavelength
Explanation
Why this works
The distance between two consecutive nodes in a stationary wave is half the wavelength, as nodes are points of no displacement that occur at regular intervals along the wave.
