Thermo/Waves Exam

Front

What are seismic waves and light waves similar in?

Back

They are both transverse waves.

Front

When comparing two wave graphs, what does a greater amplitude indicate?

Back

Wave B has a greater amplitude.

Front

What type of heat transfer is exemplified by the sun?

Back

Radiation.

Front

What does the first law of thermodynamics state in the context of a star?

Back

The energy produced through nuclear fusion in a star is converted into heat and radiated as light, maintaining energy conservation.

Front

What is the second law of thermodynamics?

Back

For a spontaneous process, the entropy of the universe increases.

Front

Define transverse waves.

Back

Waves where the particle displacement is perpendicular to the direction of wave propagation.

Front

What is amplitude in wave physics?

Back

The maximum displacement of points on a wave from its rest position.

Front

Explain the concept of frequency in waves.

Back

Frequency is the number of waves that pass a fixed point in a given amount of time, usually measured in Hertz (Hz).

Front

What is conduction in terms of heat transfer?

Back

The transfer of heat through direct contact between materials.

Front

Define convection in the context of heat transfer.

Back

The transfer of heat by the movement of fluids (liquids or gases) due to differences in density.
