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.
Yes. All three lasers must be giving off different types of light because every light source gives off its own type of light.
No. All three lasers must be giving off the same type of light because all three are lasers, and the same kind of light source gives off the same type of light.
