EMS Review

Front

What is atomic absorption/emission?

Back

Electrons absorb energy, making them jump from ground state to an excited state. This state is unstable, so the electron falls back to ground state, releasing light energy in the process.

What is the name of the distance between two consecutive peaks in a wave?

Back

Wavelength

Front

Which type of radiation has the lowest energy?

Back

Radio

Front

What happens to the energy of an electromagnetic wave as its frequency increases?

Front

Which type of radiation has the highest energy?

Back

Violet Light

Front

Define frequency in the context of waves.

Back

Frequency is the number of waves that pass a given point in one second.

Front

What is the relationship between wavelength and frequency?

Back

As wavelength increases, frequency decreases, and vice versa.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, from radio waves to gamma rays.

Front

What is the speed of light in a vacuum?

Back

Approximately 3.00 x 10^8 meters per second.

Front

What is a photon?

Back

A photon is a particle of light that carries energy.
