Which of the following represents the properties of light?

• A. Speed, Frequency, Density, Color
• B. Wavelength, Frequency, Amplitude, Speed
• C. Angle, Amplitude, Phase, Frequency
• D. Intensity, Wavelength, Speed, Reflection

Answer: (B)

The selection of wavelength, frequency, amplitude, and speed accurately reflects the fundamental properties of light.

Wavelength is a critical property because it determines the color of light in the visible spectrum and is a measure of the distance between successive peaks of the wave. Frequency represents how many wave cycles occur in a given time period and is inversely related to wavelength; higher frequency corresponds to shorter wavelengths and higher energy.

Amplitude refers to the height of the wave, which is related to the intensity or brightness of the light. Finally, speed is the constant velocity at which light travels in a vacuum, usually noted as 299,792 kilometers per second. These properties are essential for understanding how light behaves, interacts with matter, and is utilized in various technological applications in the biomedical field.

While the other choices contain individual properties that pertain to light or waves, they do not encompass the full, succinct characteristics that are commonly addressed in the study of light in both physics and biomedical engineering contexts.
