Question

at what speed does every type of electromagnetic radiation travel in a vacuum? the speed of light the speed of sound the speed of a koenigsegg jesko absolut 300,000,000 miles / second

Explanation:

Step1: Recall electromagnetic radiation properties

Electromagnetic radiation in vacuum travels at a constant speed.

Step2: Identify the speed

The speed of electromagnetic radiation in vacuum is the speed of light. The speed of sound is for mechanical waves (not electromagnetic). The speed of a Koenigsegg Jesko Absolut is a vehicle speed (much slower). 300,000,000 miles/second is incorrect (the speed of light is approximately 186,000 miles per second or \(3\times10^{8}\) meters per second).

Answer:

The speed of light
