Front

What is the relationship between temperature and kinetic energy of molecules?

Back

As temperature increases, the average kinetic energy of molecules increases.

Front

What is the definition of refraction?

Back

Refraction is the bending of light as it passes from one medium to another.

Front

What is the significance of the frequency of light in the Photoelectric Effect?

Back

The frequency of light determines whether electrons can escape from the metal.
