"peak wavelength" vs "peak wavelengths"

Question

"peak wavelength" vs "peak wavelengths"

Both 'peak wavelength' and 'peak wavelengths' are correct, but they are used in different contexts. 'Peak wavelength' is used when referring to a single wavelength that corresponds to the peak of a distribution, while 'peak wavelengths' is used when referring to multiple wavelengths that correspond to different peaks in a distribution.

Last Updated: March 21, 2024

Use 'peak wavelength' when you want to specify the wavelength that corresponds to the peak of a distribution.

Examples:

The peak wavelength of the emitted light is 550 nm.
The peak wavelength of the spectrum is in the visible range.

Alternatives:

wavelength at the peak
maximum wavelength
wavelength peak
dominant wavelength
central wavelength

Use 'peak wavelengths' when you want to refer to multiple wavelengths that correspond to different peaks in a distribution.

Examples:

The spectrum shows multiple peak wavelengths in the ultraviolet range.
The sensor detects peak wavelengths in the infrared spectrum.

Alternatives:

wavelengths at the peaks
maximum wavelengths
wavelength peaks
dominant wavelengths
central wavelengths
