Question

2 what do earthquake waves have in common with other waves?
a they travel at the same speed as light waves
b they carry the same amount of energy as sound waves
c they bend when they travel through different materials
d they have the same wavelength as radio waves

Explanation:

• Option A: Earthquake waves are much slower than light waves (light travels at ~300,000 km/s, while earthquake waves are 2-13 km/s), so this is false.
• Option B: Earthquake waves carry vastly more energy than typical sound waves, so this is false.
• Option C: All waves (including earthquake waves) undergo refraction, which is bending when passing through materials with different properties (like different rock types for earthquake waves, or different media for light/sound). This is a universal wave behavior.
• Option D: Radio waves have much longer wavelengths than earthquake waves, so this is false.

Answer:

C. They bend when they travel through different materials
