Workshop 7 Worksheet!

Front

What is a photon?

Back

A photon is a quantum of electromagnetic radiation, which can be thought of as a particle of light.

Front

What does it mean for a photon to be emitted?

Back

When a photon is emitted, it is released from an atom or molecule, typically when an electron transitions from a higher energy level to a lower energy level.

Front

What does it mean for a photon to be absorbed?

Back

When a photon is absorbed, it is taken in by an atom or molecule, causing an electron to transition from a lower energy level to a higher energy level.

Front

What is the relationship between energy and frequency of a photon?

Back

The energy of a photon is directly proportional to its frequency, described by the equation E = hf, 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 radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

What is the principle of conservation of energy in relation to photons?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed. In photon interactions, the energy of emitted or absorbed photons must equal the energy change in the atom or molecule.

Front

What is the photoelectric effect?

Back

The photoelectric effect is the phenomenon where electrons are emitted from a material when it absorbs light (photons) of sufficient energy.

Front

What is the significance of Planck's constant?

Back

Planck's constant (h) is a fundamental constant that relates the energy of a photon to its frequency, playing a key role in quantum mechanics.

Front

What is a quantum leap?

Back

A quantum leap refers to the abrupt transition of an electron between energy levels within an atom, resulting in the emission or absorption of a photon.

Front

What is the difference between continuous and discrete spectra?

Back

Continuous spectra show a full range of wavelengths, while discrete spectra consist of specific wavelengths emitted or absorbed by atoms, appearing as lines.
