Answer:
The speed of the given electromagnetic wave is 3 x 10⁸ m/s.
Step-by-step explanation:
Electromagnetic wave is a type of energy that is commonly known as light energy. The speed of light in air is about 3 x 10⁸ meters per second (m/s).
All electromagnetic waves travel at the same speed which is equal to speed of light, approximately 3 x 10⁸ meters per second (m/s) through a vacuum or air.
Therefore, the speed of the given electromagnetic wave is 3 x 10⁸ m/s.
