What is the definition of a P-wave?

Back

A primary wave that is a type of seismic wave that compresses and expands the material it travels through.

Front

What is the definition of an S-wave?

What is the difference between a white dwarf and a supergiant star?

Back

A white dwarf is a small, dense star that is the remnant of a low-mass star, while a supergiant is a massive star that has expanded and cooled.

Front

What is the significance of the Hertzsprung-Russell diagram?

Back

It classifies stars based on their luminosity, color, temperature, and evolutionary stage.
