Light, Electrons, and the Electromagnetic Spectrum Flashcard

Front

Which color of visible light carries the most energy?

Back

Violet carries the most energy among visible light colors.

Front

What is a photon best thought of as?

Back

A photon is best thought of as a packet of energy.

Front

What is the relationship between energy and frequency in light calculations?

Back

Energy and frequency have a direct relationship; as one increases, the other does too.

Front

What happens to electrons during the production of a bright line emission?

Back

Electrons absorb energy and move to an excited state.

Front

What is the equation used to calculate the energy of light?

Back

E = h * f, where E is energy, h is Planck's constant, and f is frequency.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including visible light.

Front

What is wavelength?

Back

Wavelength is the distance between successive peaks of a wave, typically measured in meters.

Front

What is frequency?

Back

Frequency is the number of waves that pass a point in one second, measured in hertz (Hz).

Front

How are wavelength and frequency related?

Back

Wavelength and frequency are inversely related; as wavelength increases, frequency decreases.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 3.00 x 10^8 meters per second.
