a pattern that describes how energy is carried from one place to another is a ___
wave
wavelength
light
energy
These graphs show the wavelength and amplitude of light coming from three lasers. Could any of these lasers be giving off a different type of light?
Yes. Laser 2 could be giving off a different type of light because Laser 2 has a different wavelength than Lasers 1 and 3.
Yes. Laser 3 could be giving off a different type of light because Laser 3 has a different amplitude than Lasers 1 and 2.
No. All three lasers must be giving off the same type of light because all three are lasers.
