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.
Answer:
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
Answer:
1:2
Explanation:
For every 4 moles of aluminum, there are 2 moles of aluminum oxide, so the mole ratio when converting from aluminum to alunmimum oxide is
2 moles aluminum oxide:4 moles aluminum. This can be simplified to 1:2.
