note: to answer some of the questions, it may help to reference a periodic table. why did max planck suggest that light had particle - like properties? because the speed that light travels through a vacuum could not be explained using its wave properties because hydrogen’s emission line spectrum could not be explained using its wave properties because how light traveled through different mediums could not be explained using its wave properties because blackbody radiation could not be explained using the wave properties of light

Answer

Brief Explanations:

Max Planck proposed light had particle - like properties to explain blackbody radiation. Classical wave theory failed to account for the observed distribution of energy in blackbody radiation. Planck's hypothesis of quantized energy (photons) resolved this issue.

Answer:

because blackbody radiation could not be explained using the wave properties of light
