What happens to an electron in an atom when it emits light?

Back

An electron drops from a higher to a lower energy level.

Front

How can you determine which of two objects is hotter?

Back

By comparing their temperatures or energy emissions.

Front

If two stars emit the same amount of energy but one is hotter, what can be inferred about their surface areas?

Back

The hotter star has a smaller surface area than the cooler star.

Front

What is the relationship between temperature and energy emission in objects?

Back

Hotter objects emit more energy than cooler objects.

Front

What is the smallest object among a set of objects?

Back

The object with the least size or mass.

Front

Why do we not see green stars?

Back

Our eyes cannot detect the green wavelength as well when other colors are also produced, making the star appear white.

Front

What is the significance of energy levels in an atom?

Back

Energy levels determine the possible states of electrons and their transitions can result in the emission or absorption of light.

Front

What is the concept of thermal radiation?

Back

Thermal radiation is the emission of electromagnetic waves from all matter that has a temperature greater than absolute zero.

Front

How does surface area affect the temperature of an object?

Back

Objects with larger surface areas can lose heat more quickly, affecting their temperature.

Front

What is the visible spectrum of light?

Back

The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye, typically ranging from 380 to 750 nanometers.
