Question

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


A. Matter behaves as particles under certain conditions.

B. Matter can absorb energy in any amount.

C. Matter can absorb light only in certain specific amounts.

D. Matter behaves as a wave under certain conditions.

Answer 1

The idea that Max Planck propose to help explain why a blackbody radiator did not give off light of increasingly high frequency as its temperature increased is that C. Matter can absorb light only in certain specific amounts. 

Answer 2

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 $10^{-34}$ J-s

v is light energy absorbed or released

Hence, matter can absorb light energy only in certain specific amounts.
