NGSS.MS-PS4-2

the change in frequency of a wave depending on how close or far you get to it.

• Doppler effect

• reflection

• refraction

• Law of Reflection

when a ray of light hits a flat surface, it reflects at the same angle that it came towards it.

• Doppler effect

• Law of Reflection

• Law of refraction

• Law of diffraction

What happens to all the wavelengths of the visible light spectrum when you see the color red?

• the red wavelength is absorbed and all others are reflected

• all the wavelengths are reflected

• the red wavelength is reflected and all others are absorbed

• all the wavelengths are absorbed
