Electromagnetic waves differ from other types of waves because they are (2 points) Group of answer choices

a. a continuous transfer of energy.

b. able to travel through a vacuum.

c. a visible form of energy.

d. able to move particles in a medium.

Why do scientists believe that light is made of streams of particles? scientists believe that light is made of streams of particles because only the presence of photons can explain phenomena observed during experiments on the photoelectric effect. these observations include only some frequencies of light causing the ejection of electrons, no time gap existing between light striking a metal and electrons being ejected, and intensity having no effect on the kinetic energy of the ejected electrons.
