Question

question 2
which of the following is a true statement about the speed at which electromagnetic waves travel through empty space?
the highest frequency types of electromanetic waves travel the fastest
all the different types of electomagnetic waves travel at the same speed
the highest amplitude types of eletromagnetic waves travel the fastest
the lowest frequency types of electromanetic waves travel the fastest

Explanation:

In a vacuum, all electromagnetic waves, regardless of frequency or amplitude, travel at the speed of light (approximately $3\times10^{8}$ m/s). This is a fundamental property of electromagnetic radiation.

Answer:

All the different types of electromagnetic waves travel at the same speed
