What idea did Max Planck propose to help explain why a blackbody radiator did not give off light of increasingly high frequency

Answer:
C). Matter can absorb light only in certain specific amounts.
Explanation:
We know that any objects that is heated give out radiation in the form of energy. Classical physics cannot be used to describes black body radiation. Thus Max Plank suggested that had to absorb energy in small packets of energy or in discrete steps. That is matter can not absorb any amount of energy, but it only does in certain amount of energy called the photons.
The energy absorbed or released can be expressed as
ΔE = n.h.v
where n is whole number 1, 2, 3, 4, 5...
h is Planks constant ( 6.626 x J-s
v is light energy absorbed or released
Hence, matter can absorb light energy only in certain specific amounts.

The heat or energy that is absorbed or released during a substance's phase shift is known as latent heat. It could go from a solid to a liquid or from a liquid to a gas, or vice versa. Enthalpy, a characteristic of heat, is connected to latent heat.
The heat that is used or lost as matter melts and transitions from a solid to a fluid form at a constant temperature is known as the latent heat of fusion.
Due to the fact that during softening the heat energy anticipated to transform the substance from solid to fluid at air pressure is the latent heat of fusion and that the temperature remains constant during the process, the "enthalpy" of fusion is a latent heat. The enthalpy change of any quantity of material during dissolution is known as the latent heat of fusion.
