### Homework 1A3

Why is the speed of the radiation constant when the frequency of EM radiation decreases?

The speed of radiation is constant because that constant is the speed of light. The only two things that can be changing within the equation of wavelength x frequency=speed of light is either the wavelength or the frequency.

In addition to what was said already, the speed of light is a constant because as the frequency decreases the wavelength increases proportionally, so speed never changes.
