The speeds of microwaves, infrared waves, and ultraviolet waves are Vm, Vi, and Vu respectively. Identify the correct combination showing the different waves in vacuum.

The speeds of microwaves, infrared waves, and ultraviolet waves are Vm, Vi, and Vu respectively. Identify the correct combination showing the different waves in vacuum. Correct Answer Vm = Vi = Vu

The correct combination is ➔ Vm = Vi = Vu. This is because, in vacuum, all the electromagnetic waves in question will travel at the same speed. The speed with which they travel in vacuum is the speed of light. (c = 3 × 108 m/s).
