Which statement is true about the model of the electromagnetic spectrum? it change the frequencies of light. it compare wavelengths of light. the color of light waves can be changed using the model. the intensities of light waves can be decreased using the model.

It helps compare wavelengths of light. Electromagnetic spectrum models that light is composed of various electromagnetic radiations of different frequencies. These range from the high-frequency gamma rays to the lowest frequency radio waves. Visible light occurs at 300 THz in the magnetic spectrum.

B.) It helps compare wavelengths of light.

Explanation:

Modeling the Electromagnetic Spectrum consists of a demonstration which illustrates the power of models, a pre-assessment activity on student understanding of exponents, an activity for students to construct and compare a different model of the spectrum than the model commonly used in textbooks and on posters, and an assessment task for students to construct their own models of the electromagnetic spectrum.

b. read the phase at the intersection of any given temperature and pressure.
