One light beam has wavelength, and frequency, fl. Another light beam has wavelength, in, and frequency, f2. Write a proportion that shows how the ratio of the wavelengths of these two light beams is related to the ratio Of their frequencies.

The question is missing. Here is the complete question.

One light beam has wavelength, , and frequency, f₁. Another light beam has wavelength, , and frequency, f₂. Write a proportion that shows how the ratio of the wavelengths of these two light beams is related to the ratio of the frequencies.

Explanation: In vacuum, eletromagnetic waves travels at a constant speed called "speed of light", whose symbol is [c] and magnitude is 3x10⁸m/s.

Speed of light, frequency and wavelength are related by the formula:

So, if one light beam has wavelength and frequency, and f₁, respectively, the second beam has wavelength and frequency f₂ and both travel at speed of light:

Then, the ratio that shows the relation between frequencies and wavelengths of these light beams is
