Question

match each term with the best description.

• continuous spectrum
• electromagnetic spectrum
• line spectrum
• spectral lines
• spectroscope
• visible light

portion of the electromagnetic spectrum that is visible to the human eye
series of bright lines at specific wavelengths specific to a type of emitted energy
spectrum similar to a rainbow with diffracted colors appearing to blend together
entire range of all possible frequencies of electromagnetic radiation
optical device spreads out spectral lines from a light source to make it visible to the human eye
spectrum separating colors into distinct lines

Explanation:

• Visible light is the part of the electromagnetic spectrum that can be seen by the human eye.
• Spectral lines are bright lines at specific wavelengths for a type of emitted energy.
• A continuous spectrum is like a rainbow with diffracted colors blending.
• The electromagnetic spectrum is the entire range of electromagnetic radiation frequencies.
• A spectroscope is an optical device that spreads out spectral lines from a light source for human viewing.
• A line spectrum separates colors into distinct lines.

Answer:

• Portion of the electromagnetic spectrum that is visible to the human eye: Visible light
• Series of bright lines at specific wavelengths specific to a type of emitted energy: Spectral lines
• Spectrum similar to a rainbow with diffracted colors appearing to blend together: Continuous spectrum
• Entire range of all possible frequencies of electromagnetic radiation: Electromagnetic spectrum
• Optical device spreads out spectral lines from a light source to make it visible to the human eye: Spectroscope
• Spectrum separating colors into distinct lines: Line spectrum
