(a) Prominent scientists, such as Sir Isaac Newton, believed that light could only travel as a particle.

(b) Scientists were convinced that light waves do not behave the same way as other waves.

(c) Scientists were unable to physcially see the wave, but they could see particles.

(d) There wasn't an effective way to share research at the time, so scientists were not aware of the data.
