P2 Honors Chemistry Ch. 3 & 4

Front

What is the Heisenberg Uncertainty Principle?

Back

It states that it is impossible to know exactly both the velocity (and therefore the energy) and position of an electron at the same time.

Front

List the Light Spectrum from highest to lowest energy.

Back

Gamma, X-rays, UV, Visible, IR, Microwave, Radio.

Front

What is a particle of light called?

Back

Photon.

Front

What does the symbol 𝞶 represent?

Back

Wavelength.

Front

What type of waves does light represent?

Back

Electromagnetic waves.

Front

What is the speed of light in a vacuum?

Back

Approximately 3.00 x 10^8 meters per second.

Front

What is the relationship between frequency and wavelength?

Back

They are inversely related; as frequency increases, wavelength decreases.

Front

What is the electromagnetic spectrum?

Back

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

Front

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

Back

E = hν, where E is energy, h is Planck's constant, and ν is frequency.

Front

What is Planck's constant?

Back

A fundamental constant used to describe the sizes of quanta, approximately 6.626 x 10^-34 Js.
