Chapter 6: Electronic Structure and Periodic Properties of Elements

This set of flashcards covers key concepts related to electromagnetic radiation, waves, and their properties as discussed in Chapter 6.

Electromagnetic radiation

A disturbance that travels through the electric and magnetic fields, carrying energy.

Wavelength (λ)

The distance measured from crest to crest of a wave, with units of length such as meters or nanometers.

Frequency (ν)

The number of wavelengths that pass a point in a specific amount of time, typically measured in Hertz (Hz) or per second (s⁻¹).

Electromagnetic spectrum

The range of all types of electromagnetic radiation, including different wavelengths and frequencies.

Photon

The smallest quantum of energy of electromagnetic radiation, often described as a tiny particle of light.

Planck's constant (h)

A very small constant, approximately 6.63 x 10^-34 J s, used in quantum mechanics to describe the energy of photons.

Speed of light (c)

The constant speed at which electromagnetic radiation travels, approximately 3.00 x 10^8 meters/second.

Relationship between wavelength and frequency

As wavelength increases, frequency decreases, and as wavelength decreases, frequency increases.

Properties of visible light

It comprises short wavelengths ranging from approximately 380 to 750 nanometers, with distinct colors having specific frequencies and wavelengths.
