Thermo/Waves Exam

Seismic waves and light waves are similar because

• They are both transverse waves.
• Both need a medium to travel.
• They have no similarities, actually.
• They are both compressional waves.

• 1.14 m
• 0.88 m
• 14 m
• 7.5 m

Which of the following best describes the application of the first law of thermodynamics in a star?

• The energy produced in the core of a star is lost to space and does not contribute to the star's luminosity.
• The energy produced through nuclear fusion in a star is converted into heat and radiated as light, maintaining energy conservation.
• The energy output from a star decreases as the star ages, with no increase in internal energy.
• A star undergoes no energy loss or gain as it evolves.
