Question

match each item with the correct statement below. discrete bundle of electromagnetic energy energy needed to move an electron from one energy level to another number of wave cycles passing a point per unit of time distance between wave crests separation of light into different wavelengths frequencies of light emitted by an element frequency atomic emission spectrum spectrum quantum wavelength photon

Explanation:

• A photon is defined as a discrete bundle of electromagnetic energy.
• The energy needed to move an electron from one energy level to another is called a quantum.
• Frequency is the number of wave cycles passing a point per unit of time.
• Wavelength is the distance between wave crests.
• Spectrum is the separation of light into different wavelengths.
• Atomic emission spectrum consists of the frequencies of light emitted by an element.

Answer:

1. discrete bundle of electromagnetic energy - photon
2. energy needed to move an electron from one energy level to another - quantum
3. number of wave cycles passing a point per unit of time - frequency
4. distance between wave crests - wavelength
5. separation of light into different wavelengths - spectrum
6. frequencies of light emitted by an element - atomic emission spectrum
