Light, Electrons, and the Electromagnetic Spectrum Flashcard

Front

What happens when an electron absorbs energy?

Back

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

Front

Which theory of light explains the interference of light?

Back

Wave theory of light.

Front

What occurs during the production of a bright line emission?

Back

Electrons absorb energy and move to an excited state.

Front

What is spectroscopy?

Back

A technique used to analyze the interaction between light and matter, often used in applications like fireworks.

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 is the electromagnetic spectrum?

Back

The range of all types of electromagnetic radiation, including visible light, radio waves, and X-rays.

Front

What is a photon?

Back

A photon is a quantum of light or electromagnetic radiation.

Front

What is the difference between wavelength and frequency?

Back

Wavelength is the distance between successive peaks of a wave, while frequency is the number of waves that pass a point in one second.

Front

What is the formula for calculating the speed of light?

Back

Speed of light (c) = wavelength (λ) × frequency (ν).

Front

What is the ground state of an electron?

Back

The lowest energy state of an electron in an atom.
