Light, Electrons, and the Electromagnetic Spectrum Flashcard

Front

What color of visible light carries the most energy?

Back

Violet carries the most energy among visible light colors.

Front

What color of visible light carries the least amount of energy?

Back

Orange carries the least amount of energy among visible light colors.

Front

What is a photon?

Back

A photon is a packet of energy.

Front

What color would an electron emit if it falls a larger distance?

Back

An electron falling a larger distance would likely emit green light.

Front

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

Back

Energy and frequency have a direct relationship; as energy increases, frequency increases.

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.

Front

How does wavelength relate to energy?

Back

Shorter wavelengths correspond to higher energy, while longer wavelengths correspond to lower energy.

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.

Front

What is the formula for calculating the energy of a photon?

Back

Energy (E) = h * frequency (ν), where h is Planck's constant.
