the number of peaks of a wave that pass in a second.
a range of wavelengths.

what is a wavelength? *
1 point
a pattern that describes how energy is carried from one place to another.
the distance from one peak of a wave to the next.
the number of peaks of a wave that pass in a second.
a range of wavelengths.

Explanation:

First Question (What is a spectrum?):

To determine the correct answer, we analyze each option:

• "A pattern that describes how energy is carried from one place to another" describes a wave, not a spectrum.
• "The distance from one peak of a wave to the next" is the definition of wavelength.
• "The number of peaks of a wave that pass in a second" is the definition of frequency.
• "A range of wavelengths" matches the definition of a spectrum (e.g., electromagnetic spectrum includes a range of wavelengths like radio, visible light, etc.).

We analyze each option:

• "A pattern that describes how energy is carried from one place to another" describes a wave.
• "The distance from one peak of a wave to the next" is the standard definition of wavelength.
• "The number of peaks of a wave that pass in a second" is frequency.
• "A range of wavelengths" is the definition of a spectrum, not wavelength.

Answer:

D. A range of wavelengths.
