The wave amplitude refers to the maximum displacement or distance from the equilibrium position of a wave. It is typically represented by the symbol "A." However, the wave amplitude cannot be determined solely from the wavelength information provided (275 nm). The wave amplitude depends on various factors, such as the specific source of the X-ray radiation, the intensity of the radiation, and the properties of the medium through which the X-rays are passing.
In general, the wave amplitude represents the magnitude of the oscillation or disturbance caused by the wave. It is typically measured in units such as meters (m) or another appropriate distance unit.
If you have additional information about the X-ray source or any other relevant details, I may be able to provide a more specific answer regarding the wave amplitude.
