Hello
The final light will be white. In fact, each color of the visible spectrum is an electromagnetic wave with its own specific frequency and wavelength. White, instead, does not have a specific frequency: it is the sum of all the different wavelengths of the visible spectrum. Therefore, when recombining the spectrum of the refracted light all the different frequencies recombine together, and their sum gives white light.

I believe that a light bulb releases visible light and a radio antenna releases a radio waves
Answer:0.69
Explanation:
Coefficient of kinetic friction=f/R=61.8/90=0.69
Do you still need help?!?!
