Which of the following is a characteristics of stationary waves?
Answer Details
Stationary waves are formed by the superposition of two waves of the same frequency and amplitude travelling in opposite directions. This means that the first characteristic listed is correct.
Stationary waves can be transverse or longitudinal, which is the second characteristic listed.
The distance between two successive nodes in a stationary wave is equal to half of the wavelength, not one wavelength as stated in the third option.
Finally, the antinode is a point of maximum displacement, not minimum displacement as stated in the fourth option.
In summary, the correct characteristics of stationary waves are: they are formed by two identical waves travelling in opposite directions, they can be transverse or longitudinal, the distance between two successive nodes is half of the wavelength, and the antinode is a point of maximum displacement.
