Description:

The application utilizes the sophisticated features of your smartphone's camera sensor coupled with advanced algorithms to analyze incoming light as accurately as possible and determine its dominant wavelength. This innovative technology broadens horizons, enabling in-depth exploration of the light spectrum within our surroundings.

For light sources with a single wavelength, such as typical colored LED lighting, the dominant wavelength directly corresponds to the light's wavelength.

Measuring Light
<ul>
 <li>Locate a white or gray surface (e.g., plain white paper)</li>
 <li>Direct your camera at the surface, ensuring only the desired light source illuminates it</li>
 <li>The application will exhibit the dominant wavelength of the light in nanometers (nm), the frequency in terahertz (THz), and the light period length in femtoseconds (fs)</li>
</ul>

Automatic Warnings
The application issues helpful notifications when conditions aren't optimal for precise measurements to assist you in obtaining accurate results.

Understanding Dominant Wavelength
Dominant wavelength is a fundamental concept in color science and perception, representing the most prominent or dominant wavelength of light perceived within a color mixture or source. Essentially, it is the wavelength that our eyes interpret as the primary color within a mix of different wavelengths. In situations where light consists of only one wavelength, like with regular LED lighting, the dominant wavelength naturally corresponds to the source's wavelength.

Measurement Accuracy
Precisely determining the dominant wavelength of light is more intricate than it appears and is further complicated on smartphones and tablets due to variations between devices. View the measurements as reliable approximations. Ensure consistent use of a white surface and isolate the target light source's illumination on that surface. Avoid any hand shadows or device reflections for dependable estimations. Under these conditions, relative measurements comparing dominant wavelengths across different light sources using the same device yield satisfactory results.

Kindly note that smartphone cameras encounter constraints in distinguishing very short or long wavelengths. Typically, these devices exhibit limited accuracy below 465 nm and above 610 nm due to inherent restrictions in their physical camera sensors. The application displays an automated warning for these extreme short and long wavelengths.
