Light, Electrons, and the Electromagnetic Spectrum Flashcard

Front

What equation is used to calculate the energy of light based on its frequency?

Back

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

Front

Which theory of light best explains the interference of light?

Back

Wave theory of light.

Front

What is the term for the state of an electron when it absorbs energy and moves to a higher energy level?

Back

Excited state.

Front

What is a practical application of spectroscopy?

Back

Spectroscopy is used in fireworks to analyze the chemical composition of elements.

Front

What does the theory of wave-particle duality state about matter?

Back

All matter has properties of both a particle and a wave.

Front

What is Planck's constant and why is it important in quantum mechanics?

Back

Planck's constant (h) is a fundamental constant that relates the energy of a photon to its frequency; it is crucial for understanding quantum mechanics.

Front

What is the electromagnetic spectrum?

Back

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

Front

How does the frequency of light relate to its energy?

Back

The energy of light is directly proportional to its frequency; higher frequency light has more energy.

Front

What phenomenon occurs when light passes through a prism?

Back

Dispersion, which separates light into its component colors.

Front

What is the photoelectric effect?

Back

The photoelectric effect is the emission of electrons from a material when it absorbs light, demonstrating the particle nature of light.
