Chemistry Week 4 Flashcard

Front

What is the frequency of a wave?

Back

The number of waves produced in a timeframe.

Front

What is a valence electron?

Back

Electrons in the outermost shell.

Front

How many valence electrons does Silicon (Si) contain?

Back

4

Front

Which color has the longest wavelength?

Back

Red.

Front

Which wave in a diagram has the greatest frequency?

Back

Wave 4.

Front

What is wavelength?

Back

The distance between successive crests of a wave.

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.

Front

What is the speed of light in a vacuum?

Back

Approximately 299,792 kilometers per second.

Front

What is the formula for calculating wave speed?

Back

Wave speed = frequency × wavelength.
