Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. How long is Wavelength?The Greek letter lambda (λ) is used to represent wavelength
2. What is the spectroscopy?The study of how matter interacts with electromagnetic radiation, often analyzing wavelengths
3. What is a wavelength and why is it important?A wavelength is the distance over which a wave repeats its shape. It tells us about a wave’s color, pitch, and energy, helping scientists understand light, sound, and many other phenomena.
4. How does wavelength relate to the colors we see in a rainbow?In visible light, different wavelengths make different colors. Red light has the longest wavelengths, while violet light has the shortest.

Transverse Wave: A wave in which the particles of the medium move perpendicular to the direction of the wave's propagation.
Longitudinal Wave: A wave in which the particles of the medium move parallel to the direction of the wave's propagation.
Electromagnetic Radiation: Energy that travels and spreads out as it goes, including radio waves, visible light, and X-rays.
