E-M Wave Formation

Front

What happens to an excited electron after it releases energy?

Back

The electron returns to the ground/lower state.

Front

What must an electron do to move to a higher energy level?

Back

Absorb energy.

Front

True or False: Some elements share the same atomic/emission spectrum.

Back

False.

Front

Why does the emission spectra of each element have different colors?

Back

The different electron configurations produce unique vibration frequencies.

Front

In E-M Waves, how do the electric wave and magnetic wave travel in relation to each other?

Back

They travel perpendicular to each other.

Front

What is an electromagnetic wave?

Back

A wave that consists of oscillating electric and magnetic fields that propagate through space.

Front

What is the relationship between frequency and wavelength in electromagnetic waves?

Back

They are inversely related; as frequency increases, wavelength decreases.

Front

What is the speed of light in a vacuum?

Back

Approximately 3.00 x 10^8 meters per second.

Front

What is the principle of superposition in wave theory?

Back

When two or more waves overlap, the resultant wave is the sum of the individual waves.

Front

What is the photoelectric effect?

Back

The emission of electrons from a material when it absorbs light or electromagnetic radiation.
