Which of the following is true about the changes to the AM signal?

• The amplitude changes.

• the frequency changes

• the wavelength changes

Which of the following is true about the changes to the FM signal?

• The amplitude changes.

• the frequency changes

• nothing changes

Tags

NGSS.MS-PS4-1

Which is true?

• AM waves have an overall longer wavelength than FM, so they can travel farther.

• AM wavelengths are shorter than FM so they can travel between the air particles.

• AM waves have wavelengths that do not change, and so they have more energy.

• AM waves have more dramatic wavelength change than FM, so they can travel through more stuff.
