Step by step solution

01

Understanding the properties and scientists

First, let's identify the main contributions of the different scientists: - Davisson and Germes: Known for their discovery of the wave nature of electrons, through the Davisson-Germer experiment. - G. P. Thomson: Also contributed to the discovery of the wave nature of electrons. - Max Planck: Known for his work on the properties of light, specifically the quantized nature of light, which resulted in him developing Planck's constant and the Planck's law of black-body radiation. - Huygens: Known for his work on the wave theory of light, which describes the properties of light as a wave rather than particles. #Step 2: Match properties with scientists#

Matching the properties and scientists

Now let's match the properties (Column-I) with the correct scientists (Column-II): - (A) Particle nature of light: Max Planck (r) - As he proposed that light energy is quantized. - (B) Wave nature of light: Huygens (s) - He developed the wave theory of light. - (C) Wave nature of slow-moving electrons: Davisson and Germes (p) - They discovered the wave nature of electrons in the Davisson-Germer experiment. - (D) Wave nature of fast-moving electrons: G. P. Thomson (q) - He also contributed to the discovery of the wave nature of electrons. #Step 3: Find the correct option#
03

Determine the correct option

With our matching of properties and scientists, we now look for which option has all the correct matches. The matching we have is: (A) \(\rightarrow\) (r), (B) \(\rightarrow\) (s), (C) \(\rightarrow\) (p), (D) \(\rightarrow\) (q) Comparing our matching with the given options, the correct answer is: Option (C): \((\mathrm{A}-\mathrm{r}),(\mathrm{B}-\mathrm{s}),(\mathrm{C}-\mathrm{p}),(\mathrm{D}-\mathrm{q})\)
