[All WGU Integrated Physical Sciences (MTC1) Questions]

Which type of wave travels faster through water than through air?

AVisible light waves

BSound waves

CRadio waves

DGamma waves

Show Suggested Answer

Suggested Answer: B

1. **Wave Propagation in Different Media**: The speed at which waves travel depends on the properties of the medium they are traveling through. 2. **Speed of Sound**: Sound waves travel faster in water than in air because water molecules are closer together than air molecules, allowing sound waves to transmit more efficiently. 3. **Comparison with Other Waves**: - **Visible Light Waves**: Travel faster in air than in water. - **Radio Waves**: Also travel faster in air than in water. - **Gamma Waves**: Travel at the speed of light and are less affected by the medium. 4. **Conclusion**: Among the given options, sound waves are the type of waves that travel faster through water than through air. **Reference**: - Wave Propagation Characteristics: The behavior of different types of waves in various media.

Definitely B) Sound waves. It makes sense with the density.

I'm pretty sure radio waves are the fastest. They can even travel through space!

I believe sound waves are the answer here, but I might be mixing it up with how light behaves in different mediums.

I’m a bit confused; I thought visible light waves travel faster in a vacuum, but not sure about water vs. air.

I remember practicing a question like this, and I think it was about how sound waves are mechanical waves, so they need a medium like water to travel faster.

Ugh, I'm drawing a blank on the wave properties. Maybe I can eliminate a few options and make an educated guess. Gamma waves seem like they'd be absorbed more in water, so I'll rule out D. Hmm, I'm stuck between B and C.

I'm pretty confident about this one. Visible light waves have a higher frequency than radio waves, so they should travel faster in both air and water. I'm going with A) Visible light waves.

Wait, I'm not sure. Aren't radio waves supposed to travel really well through water? Or is that a different type of electromagnetic wave? I'm a bit confused on the differences between the wave types.

Hmm, I think this is asking about the speed of different types of waves in different mediums. I'll need to think about the properties of each wave type and how they might behave in water versus air.
