Question

Which of the following makes Light waves unique compared to sound waves?

Light travels can move without a medium, unlike sound

Light can carry energy, unlike sound

Light's frequency can be altered, unlike sound

Light's velocity is calculated with frequency and wavelength, unlike sound

Answer 1

The statement that makes light waves unique compared to sound waves is:

**Light travels can move without a medium, unlike sound.**

Light waves are electromagnetic waves and do not require a medium to propagate, meaning they can travel through a vacuum (like space). In contrast, sound waves are mechanical waves that require a medium (such as air, water, or solids) to travel through.

While all the other statements contain elements of truth, the most distinguishing feature of light waves in comparison to sound waves is their ability to propagate without a medium.
