Pre-Lab Flashcard: Evaluate Atomic Spectra

Front

What can split a color spectrum into individual colors?

Back

A glass prism can split a color spectrum into individual colors.

Front

What is an element's signature of emitted wavelengths of light called?

Back

It is called the emission spectrum.

Front

Electromagnetic radiation travels in the form of what kind of waves?

Back

Electromagnetic radiation travels in the form of transverse waves.

Front

What food item are you igniting in this lab to determine which substances are contained in it?

Back

You are igniting a banana chip.

Front

When do atoms release photons of light?

Back

Atoms release photons of light when the electrons fall back down to a lower energy state.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including visible light.

Front

What is a photon?

Back

A photon is a particle of light that carries energy.

Front

What happens to electrons when they absorb energy?

Back

Electrons are promoted to a higher energy state when they absorb energy.

Front

What is the relationship between wavelength and frequency in electromagnetic waves?

Back

Wavelength and frequency are inversely related; as wavelength increases, frequency decreases.

Front

What is the significance of the emission spectrum in identifying elements?

Back

The emission spectrum is unique for each element, allowing for identification based on the wavelengths of light emitted.
