Question

multiple - choice question

short high energy waves travel long low energy waves.

slower than

faster than

the same speed as (c, the speed of light)

Explanation:

In a vacuum, all electromagnetic waves (regardless of being short - high energy like gamma rays or long - low energy like radio waves) have wave - particle duality and travel at the speed of light \(c\). This is a fundamental property of electromagnetic radiation.

Answer:

the same speed as (c, the speed of light)
