Light as a wave

- Davisson-Germer Experiment
Light as a particle
- Einsteins Photoelectric Effect Phenomenon
- Diffraction Phenomenon of Particles
<h2>Define the following terms:-</h2><h3>
1)Photoelectric Effect</h3>
Electrons are released when a material is exposed to electromagnetic radiation, such as light, and this is known as the photoelectric effect. These electrons are referred to as photoelectrons.
<h3>
2)Diffraction </h3>
When a wave hits a wall or an opening, several phenomena known as diffraction take place. It is described as the interference or bending of waves through an aperture into the region of the geometric shadow cast by the obstruction or aperture.
<h3>3)
Davisson-Germer Experiment</h3>
In the Davisson-Germer experiment, conducted by Clinton Davisson and Lester Germer between 1923 and 1927 at Western Electric (later Bell Labs), electrons scattered by a nickel-metal crystal's surface showed a diffraction pattern. This was an experimental turning point in the development of quantum mechanics and supported the wave-particle duality concept first put forth by Louis de Broglie in 1924.
<h3>4)
Young's Double Slit Experiment.</h3>
One of the most significant physics experiments was Young's Double Slit experiment. Thomas Young directed it in 1801. Despite the fact that Huygens' experiment had demonstrated that light has a wave character, the light at the time was still thought of as a beam of particles due to Newton's renown.

Explanation:
Answer:
No additional information is required in order to calculate the molality of the solution.
Explanation:
Mole fraction of water = 
Mole fraction of sucrose = 
From the given mole fraction of water mole fraction of sucrose can be determined.
And from both values of mole fraction moles of water and sucrose can also be calculated.
After calculating the moles of water convert them into mass of water in grams and then change that into kilograms say that be M'.
Finally we can determine the molality of solution ;
Molality of the sucrose solution ;
From this we can conclude that no additional information is required in order to calculate the molality of the solution.
Answer:
d.
Explanation:
With an ionic bond we have an elector transfer but with a covalent bond the electrons are shared to form a 'molecular' bond.
