"peak wavelength" vs "peak's wavelength"

Question

"peak wavelength" vs "peak's wavelength"

Both 'peak wavelength' and 'peak's wavelength' are correct, but they are used in different contexts. 'Peak wavelength' is the more common and concise way to refer to the wavelength at which a peak occurs. On the other hand, 'peak's wavelength' can be used when specifically referring to the wavelength belonging to a particular peak.

This phrase is used to refer to the wavelength at which a peak occurs, such as in a spectrum or graph.

Examples:

The peak wavelength of the emission spectrum is 500 nm.
The peak wavelength of the light source is in the blue region.

Alternatives:

wavelength at the peak
wavelength of the peak
maximum wavelength

This phrase is used to indicate the wavelength associated with a specific peak, emphasizing the possession by the peak.

Examples:

The peak's wavelength is 550 nm.
Can you identify the peak's wavelength on the graph?

Alternatives:

wavelength belonging to the peak
wavelength associated with the peak
wavelength of the peak

Answer 1

peak wavelength

This phrase is correct and commonly used in English.

Answer 2
