Video TranscriptIn this problem on the topic of waves and sound, we want to know which of the given waves will require a medium for its transmission, a light wave infrared wave, radio wave and a sound wave. Now, the first three are examples of electromagnetic waves, and all electromagnetic waves can propagate without a medium, so no medium is required for extraordinary ways to propagate, which is why they can propagate in vacuum. Sound waves, however, require a medium, and so we can see then that I'll answer is D. Which Carrier Sense technology is used on wireless networks to reduce collisions?
