Speed of radiation

Postby AMahadi » Tue Oct 15, 2019 3:46 pm

When does the speed of radiation decrease? What has to happen in order for it to decrease?

EM radiation doesn't change speed. Light always travels at 3.0x10^8. This is why the equation c=(lambda)v is viable.

Radiation is a form of light, just not visible light. The speed will not change in a vacuum, but it will change as it passes through a different medium, such as glass.

The speed of EM radiation will always be the speed of light (c) when in a vacuum. However, when this radiation passes through other mediums, it will slow down as it will interact with other particles/atoms/molecules in the medium.
